General Intelligence Number Series Number Series Question #6521 (CAT-I)

Find the wrong number in the following series: 8, 14, 26, 48, 98, 194, 386

A 14
B 26
C 48
D 98
Correct Answer & Explanation
Option C
• The difference between consecutive terms doubles at each step. 14 - 8 = 6 26 - 14 = 12 = (6 × 2) Next term should be 26 + 24 = 50 50 + 48 = 98 98 + 96 = 194 194 + 192 = 386 • Therefore, 48 is incorrect and should be replaced by 50.
