Sum of the terms of the series is
Sn = n/2 ( a1+an )
we have n= 6 , a1= 17, an = 57
so Sn = 6/2 ( 17+57) = 3(74) = 222

Answer:
It will take approximately 34 years
Step-by-step explanation:
If a town population is 8000 and grows 3% annually.
How long will it take to reach 16300
growth is 16300 - 8000 = 8300
using simple interest formula
SI = (P × r × t)/100
8300 = (8000 × 3 × t)100
8300= (80 × 3)t
8300 = 240t
t = 8300/240
t ≈ 34 years to the nearest tenth
