Beth started a workout program. On Monday, she did 15 sit-ups.
On Tuesday, she did 21 sit-ups, and on Wednesday, Beth did
27 sit-ups. Make a conjecture about the number of sit-ups Beth
will do on Friday.
On Friday, Beth will most likely do 39 sit ups. Every day she is doing an extra 6 sit ups.... Thursday would be 33 sit ups and Friday would be 39 sit ups.
