Which of the following options should come in place of the question mark (?) in the given series? 90 70 52 36 22 ?
10
Series: 90, 70, 52, 36, 22, ?
Consecutive differences: 70 - 90 = -20; 52 - 70 = -18; 36 - 52 = -16; 22 - 36 = -14.
The differences decrease in magnitude by 2, so the next difference is -12.
Next term = 22 + (-12) = 10.
Hence, the answer is 10.
