Enrollment was increasing at a rate of 20% per year. what was the monthly growth rate? enter your answer, rounded to the nearest tenth of a percent, in the box.

1.5%

At the end of 12 months, the multiplier for enrollment will be ...

... (1 +r)^12

for some monthly increase of r. We want to find r when that value (the multiplier for the year) is ...

... 1+20% = 1.20

Solving for r, we have ...

... (1 +r)^12 = 1.20

... 1 +r = 1.20^(1/12) . . . . take the 1/12 power of both sides

... r = 1.20^(1/12) -1 ≈ 0.0153095 ≈ 1.5%

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

-4
