Question

Find the missing term in the following series.

$2,5,9,19,37,?$

• A. $73$
• B. $75$
• C. $76$
• D. $78$

Answer 1

The correct option is B $75$

Clearly, we have: $2,2\times 2+1=5,5\times 2-1=9,9\times 2+1=19,19\times 2-1=37$, ......
So, missing term $=37\times 2+1=75$.
Hence, the answer is (B).
