Show that hn = t2n − 1. for all positive integers n where hn is the nth hexagonal number, defined in Exercise, and t2n − 1 is the (2n − 1)st triangular number.
Exercise
a) Define the hexagonal numbers hn for n = 1, 2, . . . in a manner analogous to the definitions of triangular, square, and pentagonal numbers. (Recall that a hexagon is a six-sided polygon.)
b) Find a closed formula for hexagonal numbers.
