Find the 8th term of an exponential sequence whose first is 3

3r^7

whatever r is

To find the 8th term of an exponential sequence, we need to know the common ratio (r). Without this information, we cannot determine the 8th term.

However, let me explain how to find the nth term of an exponential sequence using the given first term and common ratio:

The formula to find the nth term of an exponential sequence is given by:
tn = a * r^(n-1)

Where:
- tn is the nth term,
- a is the first term, and
- r is the common ratio.

For example, if the first term (a) is 3 and the common ratio (r) is 2, we can find the 8th term (t8) as follows:
t8 = 3 * 2^(8-1)
= 3 * 2^7
= 3 * 128
= 384

Therefore, if the common ratio is 2, the 8th term of this exponential sequence is 384.
