Question

Jack decided to start exercising. The first day he jogged for 20 minutes. The next day he wanted to Jog for 3 minutes more then the Pervious day. He wanted to continue increasing by the same amount like this for every one of the days in a week.

If he succeeded in doing this how many total did he run for the week?
(Find the 7th term first)

Answer 1

The start number is 20, because he first ran 20 minutes. If increasing by 3 each time to represent 3 more minutes, you have to make a pattern increasing (+3) every time

Explanation:

Start-> 20

Increase +3

Make Pattern= 20, 23, 26, 29, 32, 35, 38, 41, 44, 47, 50

Find the 7th Term

20 (1), 23 (2), 26 (3), 29 (4), 32 (5), 35 (6), 38 (7), 41 (8), 44 (9), 47 (10), 50 (11)

38 is the 7th Term in the pattern

Hope this helped :)
