Question

Complete the series by finding the missing term from the given alternatives.
$2,3,10,15,26,?$

• A. $37$
• B. $36$
• C. $35$
• D. $48$

Answer 1

The correct option is C $35$

Each term is of the type
$n^2+1$ and $n^2-1$, alternately,

$2=1^1+1$
$3=2^2-1$
$10=3^2+1$

$15=4^2-1$

$26=5^2+1$

So next term should be:

$6^2-1=35$ (option C)
