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
