Question

A runner's journal shows the number of miles run each day for a week:

Sunday: 3 miles
Monday: 5 miles.
Tuesday: 7 miles
Wednesday: 9 miles
Thursday: 11 miles
Friday: 13 miles
Saturday:
Based on the arithmetic sequence how many miles are planned for Saturday?

Answer 1

15 miles.
The runner adds two miles every day, so if they continue that pattern, they will run 15 miles on Saturday (13+2)
