Question

A bacteria culture begins with 13 bacteria which triple in amount at the end of every hour. How many bacteria are grown during the 10th hour?

Answer 1

255,879

Geometric Sequence Formula

`a_n = a1r^((n-1))\\\\a_1 :13\\\\r:3\\\\n:10\\`

Steps:

`a_1_0=13 (3)^((10-1))\\\\a_1_0=13(3)^((9))\\\\a_1_0=(13)19683\\\\a_1_0=255,879`
