What is the sum of a 7–term geometric series if the first term is –6, the last term is –24,576, and the common ratio is 4?
Sadie Ackerman
# S_7 = -32 768 #
The sum to n terms of a geometric series is found using:
where a is the first term and r , the common ratio.
here a = - 6 and r = 4

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
