A sequence is defined recursively by the formula f(n + 1) = f(n) + 3 . The first term of the sequence is –4. What is the next term in the sequence?

using *n *notation is just a fancy way of describing a sequence.

*n *is the number you're currently at, so with that logic *n+1 *is the term after it in the sequence.

*f(n)* is the function using *n* as the input.

so you know that the first term of the sequence is -4, or *f(n)=* -4.
