Answer:
Explanation:
5th term is 6 and the 7th term is 48, we know the nth term for a GP is arn−1
so let's substitute the given information in that formula for the nth term
ar3=6
ar6=48
ar6ar3=486
The a
and a
cancelout hence we remain with r3=8
take a cube root on both sides and we end up having r=2
Substitute the value of r in any given equation to get the value of a
ar3=6
a(2)3=6
8a=6
a=34
The formula for the nth term of this GP is given by 34(2n−1)
And when you substitute the value of n in the above formula of nth term you will get the following values; 3/4, 3/2, 3, 6…
