Given a partial sum of a geometric sequence:
a. Find a formula for the nth term, ??, explicitly.
b. Find the exact value for the partial sum.
Expert Solution
Step 1
a)
The general form of Geometric Progression is:
a, ar, ar2, ar3, ar4,…,an
Where,
a = First term
r = common ratio
The common ratio is defined as when we divide the term by its previous term then the value obtained is termed as a common ratio.
an = nth term
The formula for the nth term of the g.p is given by
.......(1)
Step 2
b)
Here, the given sequence is
The first term is .
The common ratio is .
The formula for the nth term of the g.p is given by
