Kanga likes jumping on the number line. She always makes two large jumps of length 3, followed by three small jumps of length 1, as shown, and then repeats this over and over again. She starts jumping at 0. Which of these numbers will Kanga land on?
A. 82 B. 83 C. 84 D. 85 E. 86
C.
Each time she completes a set of five jumps, Kanga moves forward 9 places on the number line. Since she started at 0, this means she will eventually land on 9 × 9 = 81. Her next set of jumps will take her to 84, 87, 88, 89 and 90. Therefore, of the numbers given, the only one Kanga will land on is 84.
