Answer:
A) 2 miles, 5 miles, 8 miles
Step-by-step explanation:
Let's get some details cleared.
[tex]a_n=a_{n-1}+3[/tex]
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 [tex]a_1[/tex] is, so we can use that as our starting point.
[tex]a_1=2\\a_2=a_1+3=2+3=5\\a_3=a_2+3=5+3=8\\[/tex]
Your answer is A.
