Home | Help Guides: Number sequence testing
Number sequences are often part of numerical aptitude, psychometric and IQ tests to identify the respondent's ability with numbers. A number sequence consists of a number series, with one missing number that respondents need to logically identify.
FlexiQuiz software helps you build your own numeracy tests that can be configured to meet your specific needs. You can create challenging, measurable tests to identify the best candidate for your organization.

Top Tips:
a) A common difference between each number
3, 6, 9, 12 .....
solution: the missing number is 15. The common difference between each number in the sequence is 3
b) 2 rules working together
5, 5, 15, 75, 525 .....
solution: the missing number is 4725. The series is made using 2 different operations (multiplication and division).
multiply each number by the previous number and increase the multiplication value by 2 each time. This is the calculation:
5 - starting number
5 * 1 = 5
5 * (1 + 2) = 15
15 * (3 + 2) = 75
75 * (5 + 2) = 525
525 * (7+2) = 4725
c) 2 rules alternating in the sequence
1, 9, 3, 6, 5 .....
solution: the missing number is 3
starting from number 1, every other number increases by 2
starting from 9, every other number decreases by 3
