Question

A series is given with one term missing. Select the correct alternative from the given ones that will complete the series. 127, 63, 31, 15, 7, ?

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

Answer:

B. 3

127 – 1 = 126;

126 ÷ 2 = 63,

63 – 1 = 62;

62 ÷ 2 = 31,

31 – 1 = 30;

30 ÷ 2 = 15,

15 – 1 = 14;

14 ÷ 2 = 7,

7 – 1 = 6;

6 ÷ 2 = 3
