Question

Please help I’m struggling help!!!!! ;(

Answer 1

Answer: Option B.

Step-by-step explanation:

A recursive formula is written as:

aₙ = aₙ₋₁*13

Now, if the first term is 7, then:

a₁ = 7

This means that:

a₂ = 7*13

a₃ = (7*13)*13 = 7*(13)^2

a₄ = (7*13^2)*13 = 7*(13)^3

You already can see the pattern here, the n-th term will be written as:

aₙ = 7*(13)^(n - 1)

Then the correct option is B
