Question

Please help me with some Algebra 2!

Answer 1

Answer:

12750

Step-by-step 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

$S_{n}$ = $\frac{a(r^n-1)}{r-1}$ ( a is the first term )

$S_{8}$ = $\frac{50(2^8-1}{2-1}$ = 50 × 255 = 12750
