What should come in place of ? in the given series?
10, 21, 43, 87, 175, ?
Given series:
10, 21, 43, 87, 175, ?
Logic "multiply by 2 and then add 1":
Starting with 10:
10 × 2 + 1 = 20 + 1 = 21
21 × 2 + 1 = 42 + 1 = 43
43 × 2 + 1 = 86 + 1 = 87
87 × 2 + 1 = 174 + 1 = 175
Now, following the same pattern for the next term:
175 × 2 + 1 = 350 + 1 = 351
The next term in the series is 351.
Thus, the correct answer is (B) 351.
