Question

You rent an apartment that costs $1700 per month during the first year, but the rent

is set to go up $70 per year. Write a recursive formula to show what the rent is during.
the nth year of living in the apartment.

Answer 1

so the first year is $1700

in that case: a(1)=1700

each year it goes up by $70

then in nth year it's: a(n)=a(n-1)+70
