Question

45. Find out the number which will replace the question mark in the given square ? 5 3 6 6 51 39 8 7 7 (1) 4 (2) 6 (3) 9 (4) 2​

Answer 1

Answer:

We see that certain numbers are missing in the given series. We will first figure out the numbers missing and the relationship between them. This is a necessary step to determine if the '?' will be replaced with a number after a missing number or it'll continue as the series.

The missing numbers are,

1,5,10,16

We see that the numbers missing are- 1,5 and two digit numbers are 10,16- the sum of the two numbers of the two digit numbers are 1+0=1 and 1+6=7

We see that the series is omitting odd numbers or 2 digit numbers where the sum of the two digits is an odd number.

So the next number should be 22.

Option A is the correct answer.
