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
