1st term

= 1 (given)

2nd term

= 1 + 4 = 53rd term

= 5 + 4 = 9We have

5 ans choices each expression contains

n which is the number of terms

Equating each expression with a term in our sequence should give us the ans

let us suppose 2nd term which is

5Among the ans choices whichever returns with a value for

n = 2 is the ans

option c does exactly that when

4n -3 =5or,

4n = 8 hence,

n = 2 option c
