Question

Which recursive formula represents the sequence that represents the pattern?

Answer 1

A

Explanation:

a recursive formula allows a term in the sequence to be found from the preceding term.

here the pattern of squares is

1, 4, 16

each term is 4 times the preceding term

then recursive formula is

`a_(n)` = 4
`a_(n-1)` : a₁ = 1
