What should be missing term in the following number series ?
8, 6, 17, 14, 35, 30, 71, ?, 143
Correct Answer: Option A
We will start form the 3rd number. 3rd number = 1st number × 2 + 1
Similary, we will apply for the next number also.
So, we have the terms of the series as
⇒17 = (8) × 2 + 1
⇒14 = (6) × 2 + 2
⇒35 = (17) × 2 + 1
⇒30 = (14) × 2 + 2
⇒71 = (35) × 2 + 1
⇒? = (30) × 2 + 2
⇒? = 62
⇒143 = (71) × 2 + 1
