Question

A tuition scale for a state university shows an increase of $1,300 each year.

Part 1: If the initial cost was $21,000, what will the cost of tuition be in twenty three years? (5 points)

Part 2: In complete sentences, explain how an arithmetic sequence was applied. (4 points)

Answer 1

Would Part 1 be $50,900?

Answer 2

21,000+(23*1300)

Answer 3

i get 50900

Answer 4

arithmetic sequence was applied because there is a common difference of 1300. You can just apply the formula with all the givens.

Answer 5

Would this work for part 2...

Answer 6

The sequence I used is T = R • t + I. I used this because the tuition follows a steady sequence, we can move forward or backward in the sequence to know the cost of tuition by multiplying the rate of increase by the time and adding it to the starting cost of tuition.
