a.
b.
c.
d.

Option B -

Step-by-step explanation:

Given : Sequence 5, 13, 29, 61, 125, ...

To find : Which recursive formula describes the sequence below?

Solution :

To find which function gives recursive formula substitute the value and check which satisfy the given sequence.

A.

Finding 2 term put n=2

Applicable as second term is 13.

Check for third term put n=3

Not applicable as third term is 29.

B.

Finding 2 term put n=2

Applicable as second term is 13.

Check for third term put n=3

Applicable as third term is 29.

C.

Finding 2 term put n=2

Applicable as second term is 13.

Check for third term put n=3

Not applicable as third term is 29.

D.

Finding 2 term put n=2

Applicable as second term is 13.

Check for third term put n=3

Not applicable as third term is 29.

Therefore, Only Option B is correct as it form the recursive formula of given sequence.
