Question

Daniel decided to take part in a 10-day fitness challenge for his PE class. Each day, Daniel has to do 5 more push-ups than he did the day before. If Daniel did 20 push-ups on the first day of the challenge, how many total push-ups will he have done during the 10-day challenge?​

Answer 1

The answer is 495

Explanation:

If you need to add 5 more push-ups every day and find the total it would be 20+25+30+35+40+45+50+55+60+65+70=495
