Please substitute this for one of my paragraphs:

Now we're going to create another sequence. Look at the coefficient of X for the sum of the zero-th powers. The formula was X + 1. The coefficient for X was 1. The coefficient means the number that the variable is multiplied by in the formula.

I forgot the words "of X."
