By “telescopic” addition of these n – 1 equations, the left side becomes f(n) – f(1). The right side is 2 + 3 + · · · + n. Therefore,

When a sequence is defined by giving the initial term (or initial terms) and a formula for finding the successor of any term, we say that the sequence is defined recursively.

6-2Each of the following (partial) tables has a function rule associating a value of n with its corresponding value f(n). If f(n) = An + B, determine for each case the numerical values of A and B.
