Question:
You rent an apartment that costs $1700 per month during the first year, but the rent is set to go up $110 per year. What would be the monthly rent during the 11th year of living in the apartment?
Answer:
Arithmetic Sequence: d=110 or a11 = 2800
Step-by-step explanation:
Write out the first 3 terms:
a 1 = 1700 ←rent in 1st year
a 2 =1810←rent in 2nd year
a 3 =1920←rent in 3rd year
Arithmetic Sequence: d=110
Explicit Formula:
an=a 1+(n−1)d
a 11 =1700+(11−1)(110)1700+(11−1)(110)
a11=2800
