Question

A geometric sequence has first term a = 900 and common ratio r = 3. Findthe 5th term of the sequence.

Answer 1

A geometric sequence with the following details given;

Given:

$\begin{gathered} a=900 \\ r=3 \\ n=5 \\ U_5=? \end{gathered}$

The nth term of a geometric sequence is given by;

$U_n=ar^{n-1}$

Substituting the given values in the formula, we have;

$undefined$
