Answer 2

Answer:

Missing number in the series is 123

Step-by-step explanation:

The given series is 3,11,27,59,_,251

Difference between second term and first term = 11 -3 = 8 =$2^{3}$

Difference between third term and second term = 27 - 11 =16 =$2^{4}$

Difference between fourth term and third term = 59 - 27 = 32 =$2^{5}$

So difference between fifth term and fourth term =  $2^{6}$ = 64

∴ next term = 59 +64= 123
