Q:
# Find the 91st term of the arithmetic sequence 28, 8, -12, ...28,8,β12,...

Accepted Solution

A:

Since there are only three terms and they repeat we can easily figure this out.To do that all we have to do is determine how far away 91 is from a multiple of three. If it lands on a multiple of three it will be -12. If it is two above a multiple of three it will be eight. If it is one above a multiple of three it will be 28.So the 91st term in one above a multiple of three the answer will be 28.
