Q. Mandy did 22 sit-ups on Monday, 66 sit-ups on Tuesday, 1818 sit-ups on Wednesday, and 5454 sit-ups on Thursday. What kind of sequence is this?
  1. List Sit-ups Count: Step 11: List the number of sit-ups Mandy did each day.\newlineMonday: 22\newlineTuesday: 66\newlineWednesday: 1818\newlineThursday: 5454\newlineSequence: 2,6,18,542, 6, 18, 54
  2. Check Differences: Step 22: Check if the differences between consecutive terms are equal.\newline6−2=46 - 2 = 4\newline18−6=1218 - 6 = 12\newline54−18=3654 - 18 = 36\newlineThe differences are not equal.
  3. Check Ratios: Step 33: Check if the ratios of consecutive terms are equal. \newline62=3\frac{6}{2} = 3\newline186=3\frac{18}{6} = 3\newline5418=3\frac{54}{18} = 3\newlineThe ratios are equal and each term is 33 times the previous term.
