Amanda’s Training Continues…..Amanda is training to run a marathon. She must follow a strict schedule to make sure she is ready
Paladinen [302]

Based on her on training regiment, Amanda will be able to run 26 miles in the 25th week.

<h3 /><h3>What is the total number of miles Amanda will run every week?</h3>

Amanda will run 2 miles in the first week and then 1 less mile in the following week. Then 3 more miles in the week after.

Week 1 - 2 miles

Week 2:

= 2 - 1

= 1 mile

Week 3:

= 1 + 3

= 4 miles

Week 4:

= 4 - 1

= 3 miles

Week 5:

= 3 + 3

= 6 miles

From the given pattern, Amanda increase the number of miles ran by 2 miles every 2 weeks.

The number of miles ran every other week would therefore be:

Week 7 = 8 miles

Week 9 = 10 miles

Week 11 = 12 miles

Week 15 = 16 miles

Week 19 = 20 miles

Week 25 = 26 miles

In conclusion, she would reach her goal in 25 weeks.
