Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
Answer:
im pretty sure it’s a line graph
Step-by-step explanation:
it would make the most sense because the years are going in chronological order
(54.3+56.1+n)/3 = 55
54.3+56.1+n = 165
54.6 = n
The answer is 12.
The exact answer is 11.74734012..... this question is basically asking you to round the exact answer.
