Question

Find out the missing term in the series.
$4,10,28,?,244$

• A. $64$
• B. $81$
• C. $82$
• D. $96$

Answer 1

The correct option is C $82$

The given series $4,10,28,?,244$ follow a pattern :

$3^1+1=4$,

$3^2+1=10$,

$3^3+1=28$,

$3^4+1=82$,

$3^5+1=244$.

Thus, $82$ replaces question mark.

(Alternate Method)

$4+6=10$,

$10+6\times 3=10+18=28$,

$28+18\times 3=28+54=82$,

$82+54\times 3=82+162=244$.
