What is the recursive formula for this geometric sequence?
-3, -21, -147, -1029,

.

If we know the term and the common relation, r, of a geometric sequence, you can find the term using the recursive formula .

The first term of the geometric sequence is a₁ = -3.

The common relation we have to find the relationship between a term and the term that precedes it.

The recursive formula is:
