Question

Please help me with some Algebra 2!

Answer 1

12750

Explanation:

The sequence of visitors is

50, 100, 200, 400, .....

This is a geometric sequence

with common ratio r = 2

The sum to n terms is found using

`S_(n)` =
`(a(r^n-1))/(r-1)` ( a is the first term )

`S_(8)` =
`(50(2^8-1)/(2-1)` = 50 × 255 = 12750
