How many different arithmetic sequences are there with all of the following properties:
The first term is 121.
The last term is 1.
The common difference is a whole number.
The total number of terms is at least 3.
I think it's 16 but I'm not sure
Here is a place to start:
121 -1 = 120
All factors of 120 include 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120 ( The red ones will not result in 3 terms)
