Question

Complete the sequence: 21, 42, 43, 24, __, 126

Answer 1

44 is the answer for the above question

Answer 2

The answer will be 125

21, 42, 43, 24, ___ and 126

First, the last number is 1, 2, 3, 4, and 6 so the missing is 5

For the first three numbers,

21 + 11 = 42

42 + 1 = 43

Then the last three numbers,

Since 43 is obtained by adding 1 hence, the missing number is 125, then 124 – 24 = 101 that is just a 0 in between 11.
