Jeremy is writing a novel. He begins his writing session on page 10, and each minute he writes 2 additional pages.

Question

Let h(n) represent the page number Jeremy is on at the beginning of the nth minute of his writing session.
a. Is it arithmetic or geometric?
b. Write in recursive formula.

Answer 1

a. It is an arithmetic sequence because Jeremy is adding a constant number of pages (2) at each interval of time (1 minute).

b. h(1) = 10
h(n) = h(n-1) + 2, for n > 1
