Scott has decided to add push-ups to his daily exercise routine. He is keeping track of the number of push-ups he completes each day in the bar graph below, with day one showing he completed three push-ups. After four days, Scott is certain he can continue this pattern of increasing the number of push-ups he completes each day. Day 1- 3, Day 2- 5, Day 3- 7, Day 4- 9
How many push-ups will Scott do on day 10?
How many push-ups will Scott do on day 20?
How many push-ups can Scott expect to do after 4 weeks?
Lisa is also including push-ups in her workout and says she does more push-ups than Scott because she does fifteen push-ups every day. Is she correct? Explain.
Can someone do this in explicit formula- f(x)=f(1)+d(x-1) - I just started arithmetic and geometric sequences
