16, 32, 14, 19, 37, 21, 22, 42, ?, 25, 47, 35
Option 1: 34
Option 2: 26
Option 3: 32
Option 4: 28
Correct Answer: 28
Solution :
Given:
16, 32, 14, 19, 37, 21, 22, 42, ?, 25, 47, 35
The series split into three subseries:
(I)16, 19, 22,25
(II) 32, 37, 42,47
(III) 14, 21, ?, 35
In series I add 3, in II add 5 and in III add 7 as shown in the diagram below.
So, the required number is 28. Hence, the fourth option is correct.
