Finding the General term of arithmetic sequences!!!

By: Elijah B Lewis

Today i learned and taught my class how to solve general arithmetic sequences. I taught them to write out the sequence. Set up the formula An = A1+(n-1)d. A1 being the first subscript of the sequence. Find d(the common difference) the which is the number it takes for one number to reach the next. Plug in the information & find subscript n without having to write out a long sequence.
