# How do you tell whether the sequence #100, 50, 25, 25/2, 25/4,...# is geometric?

The sequence is geometric with first term

The ratio of successive term and preceeding term is constant

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.

- How do you write the nth term rule for the sequence #4,1,-2,-5,-8,...#?
- Given the first term and the common difference of an arithmetic sequence how do you find the first five terms and explicit formula: a1 = 28, d=10?
- What is a possible explicit rule for the nth term of the sequence: #25, 15, 5, -5, -15#?
- How do you find the first five terms in the geometric sequence which is such that the sum of the 1st and 3rd terms is 50, and the sum of the 2nd and 4th terms is 150?
