How To Do Number Sequence Tests
Look at the sequence and work out which of the five numbers below it is the next member of the sequence. Find the common ratio more specifically the ratio between a particular term and the term that immediately precedes it.

How to tackle different types of number sequence questions.
How to do number sequence tests. For example 23 31 37. Number sequences are regularly used in aptitude tests psychometric assessments and IQ-tests as an indication for the testees ability to reason with numbers. Check that the pattern is correct for the whole sequence from 8 to 32.
In the sequence above in step 1 you should have 5n as one part of the general term. Monotonic sequences always involve adding and subtracting as the operations. Press the Ctrl Shift Enter Keys together to finish the formula.
A number sequences test contains number sequences which are given as finite sequences of numbers in certain patterns. What comes next in the sequence 10 50 250 1250. The test requires you to deduce this logical pattern from the numerical sequence and find the next number in the order.
Multiply the common difference to n the term number. To find the pattern look closely at 24 28 and 32. So the missing terms are 8 4 12 and 16 4 20.
In the second example each number in the series is the previous number divided by 2 or multiplied by ½ or a n1 a n X 12. Prime Numbers each number in the sequence is a prime number. The pattern from the first to the second number is that the first number is doubled and then 2 is added to it.
To solve them all you have to do is figure out the pattern and come up with the next logical number of the sequence. After you have detected the rule you can then deduce the missing number. Each number in the first sequence is obtained by multiplying the previous number by 3 which we could write as a n1 a n X 3.
From the second to the third number it is simply divided by 2. The monotonic relationship is present here but now it creates a decreasing line. Explicit number sequences can easily be solved by giving the sequence a formula like the sequence shown above.
They are given as finite sequences of numbers in certain patterns. Examples of number sequence patterns. Horizontal Sequences This is the most popular format of number series questions in cognitive ability tests.
The test will start with two example questions which will not be marked or timed. In this case the answer is 84 94 minus 10. The formula for this sequence is 2n1 for the nth term meaning that you can chose any integer number for the letter n in the formula and it will generate a number in the sequence for instance.
Now click on the First Question button below to begin. 25 x 2 is 50 plus 2 gives you 52. Your performance in the Number sequence tests reflects your numerical reasoning skills.
You are to determine which pattern applies and select the right answer. If Geometric Series. 26 x 2 is 52 plus 2 is 54.
Study the example below and try the tests. Number series aptitude questions present you with mathematical sequences that follow a logical rule based on elementary arithmetic. Each term in the number sequence is formed by adding 4 to the preceding number.
You are then asked to find the rule that connects them to each other. A1A30 range of numbers the sequence to check against is from 1 to 30 2. Several different patterns are used in Number Sequences Tests.
Copy down the formula until you get NUM. In a Number Sequences Test you are asked to find a connection between given numbers in a sequence and choose the right number that comes next. Then the first pattern repeats again.
Number sequence tests use numerical data that is arranged following a logical pattern. Errors meaning all missing numbers have been listed. In this sequence you get the next number by subtracting 10 from the previous number.
To solve them all you have to do is figure out the pattern and come up with the next logical number of the sequence. N3 will generate 23-1 5 as shown in the example. In these questions a sequence of numbers called terms are presented with 1 or more missing elements.
You are asked to complete the next numbers in a sequence of 4 to 8 numbers. This means that the the next number will be 542 which is 27. You may be asked to complete the last onetwo missing values or a missing value within the series.
