20,15,11. find the reclusive and explicit equations

Recursive equation and where, n = 1, 2, 3, 4, ........ .

Explicit equation .

Step-by-step explanation:

The given series is an G.P. series and the common ratio is 0.75.

Now, the terms are 20, 15, 11.25, .......

Therefore, the explicit equation of the series will be

Again, the recursive equation of the given G.P. series will be
