Question

Olivia read a book. She started on page 20, and each minute she read 3 pages. Let g(n) be the page Olivia was on at the beginning of the n^th minute.

Answer 1

g(n)  = 3n + 17  , Olivia started on page 20, and each minute she read 3 pages

Step-by-step explanation:

Oliva started on page 20,

each minute she read 3 pages.

=> after 1 minute ( at beginning of 2nd Miute)

She will be on Page = 20 + 1 * 3 = 23   page

= 20 + (2 - 1) * 3

g(n)  at Beginning of nth Minute  = 20  +  (n - 1)* 3

g(n)  = 20 +  3n - 3

=> g(n)  = 3n + 17
