Which is the recursive formula for finding the nth term in a geometric sequence?

Let see how to build up this formula that is going to give that term of rank n

1st term = a₁ & r is the ratio

1st a₁ = a₁ x r°

2nd a₂ = a₁ x r¹

3rd a₃ = a₁ x r²

4th a₄ = a₁ x r³

5th a₅ = a₁ x r⁴

...

...

nth : a (n) = a₁ x r ⁽ⁿ-¹)

Note when that the subscript of a is the same as the exponent mines 1
