A city has a population of 30,000 people. Suppose that each year the population grows by 3.7% . What will the population be after 6 years?

i multiplied 30,000 by 6 then 3.7 and got 7425000 i don't think thats the answer i feel like im missing a step..

You certainly are missing a step. Let the growth rate r=1.037

Year 1: p1 = 30000

year 2: p2 = p1 * 1.037 = 30000 * 1.037 = 3110

year 3: p3 = p2 * 1.037 = 31110 * 1.037 = 32261

Nite that p2 = p1*r

p3 = p2*r = p1 * r^2

see a pattern here? No, go back to your text.

pn = p1 * r^(n-1)

Now you should be able to get p6
