Hiya!

Solving this problem is going to be alot easier than you think.

Week One has our starting number, 10. each week, we add four to show that he is able to run 4 extra minutes.

STARTING WEEK(1): 10 mins

WEEK 2; 10 + 4 = 14

WEEK 3; 14 + 4 = 18

WEEK 4; 18 + 4 = 22

WEEK 5; 26

WEEK 6; 30

Therefore, Dean can run for 30 minutes after week 6. Hope this helps you!
