Question

The total number of miles Jeremy walked on a hike can be represented by using the formula an=an-1 +3. If a1=2 and n

represents the total number of hours walked, what is the total distance Jeremy walked at the end of each of the first three
hours?
A) 2 miles, 5 miles, 8 miles
B) miles, 6 miles, 18 miles
C) miles, 3 miles, 4 miles
D) miles, 4 miles, 6 miles

Answer 1

A. 2 miles, 5 miles, 8 miles

Explanation:

Answer 2

A) 2 miles, 5 miles, 8 miles

Explanation:

Let's get some details cleared.

`a_n=a_(n-1)+3`

We're interested in finding how many miles he walked at the end of each hour in a period of 3 hours.

We know what
`a_1` is, so we can use that as our starting point.

`a_1=2\\a_2=a_1+3=2+3=5\\a_3=a_2+3=5+3=8\\`

Your answer is A.
