Answer:
Step-by-step explanation:
7 * 2 = 14 – 1 = 13
13 * 2 = 26 + 3 = 29
29 * 2 = 58 – 5 = 53
53 * 2 = 106 + 7 = 113
113 * 2 = 226 – 9 = 217
Like this we solve the next series by multiplying 2 and subtracting and adding alternate numbers to that
5 * 2 = 10 – 1 = 9
9 * 2 = 18 + 3 = 21
21 * 2 = 42 – 5 = 37
37 * 2 = 74 + 7 = 81
81 * 2 = 162 – 9 = 153
