Question

Select the number from among the given options that can replace the question mark (?) in the following series.
3, 11, 27, 59, ?

A.

121

B.

129

C.

122

D.

123

Correct option is D

Given series: 3, 11, 27, 59, ?
To find the pattern, observe the differences between consecutive terms:
11 - 3 = 8
27 - 11 = 16
59 - 27 = 32
Notice that the differences are doubling each time: 8, 16, 32.
Following this pattern, the next difference should be 64 (double of 32).
Therefore, the next term in the series is: 59 + 64 = 123.
Thus, the correct answer is (d) 123.
