Jenna did 5 sit-ups on Saturday, 7 sit-ups on Sunday, 10 sit-ups on Monday, 14 sit-ups on Tuesday, and 19 sit-ups on Wednesday. If this pattern continues, how many sit-ups will Jenna do on Thursday?
the answer is 25 as the numbers are consecutively being added. so on monday they did 5 and on sunday they did 7 (7-5=2) on sunday they did 7 and on monday they did 10 (10-7=3) and on monday they did 10 and on tuesday they did 14 (14-10=4)
