Question

Find an explicit formula for the geometric sequence -
d(n) =(

Answer 1

`d(n) = d(1) * r^((n - 1))`

Explanation:

For a geometric sequence, we have to find the explicit formula for the nth term.

If d(1) is the first term of a geometric sequence with common ratio r, then the sequence is given by :

d(1), d(1) × r, d(1) × r², d(1) × r³, .......

Therefore, the nth term of the sequence is given by

`d(n) = d(1) * r^((n - 1))` and this id the explicit formula. (Answer)
