Answer 2

Given:

3 4 6 9 12 18 24 31​

To find:

The wrong number in the series.

Solution:

• It is a series with growing pattern.
• To find the wrong number find the pattern of the series.
• Here the pattern is: subtract the second term with the first term, continue the same for the other terms also.(t2 - t1 , t3 - t2 ...)
• The result observed is: a series of natural numbers(1,2,3...)

4-3=1

6-4=2

9-6=3

12-9=3

18-12=6

24-18=6

31-24=7

Here the term t5=12,t6=18 is wrong because its term difference does not form a continuous natural number pattern.

So the wrong numbers in the series are 12 and 18.
