54, 56, 61, ? 88, 114

• A. 66
• B. 69
• C. 71
• D. 77
• E. none of these

Answer 1

The correct option is C 71

Given pattern,

$54,56,61,?88,114$

Now, consider,

$54+(1^2+1)=54+2=56$

$56+(2^2+1)=56+5=61$

$61+(3^2+1)=61+10=71$

$71+(4^2+1)=71+17=88$

$88+(5^2+1)=88+26=114$

Therefore option $C$ is correct.
