Use Exercise to find a formula for
(Compare with Exercise 2.)
Exercise 1
Suppose that Δan = bn Show that
This formula is analogous to the calculus formula where Dg = f (D is the derivative operator). In the calculus formula, sum is replaced by integral, and Δ is replaced by derivative.
Exercise 2
By experimenting with small values of n, guess a formula for
the given sum.
then use induction to verify your formula.
