Question

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

Answer 1

Answer:

$d(n) = d(1) \times r^{(n - 1)}$

Step-by-step 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  

$d(n) = d(1) \times r^{(n - 1)}$ and this id the explicit formula. (Answer)
