Answer 1

Answer:

31 is the correct answer for the question

Answer 2

The missing number (?) = 31

Step-by-step explanation:

The given sequence:

5, 2, 17, 4, (?), 6, 47, 8, 65​

To find, the missing number (?) = ?

The given sequence have two sequences.

The first sequence(odd places):

5, 17, ?, 47, 65

The pattern follow:

+ 12, + 14, + 16, + 18, ...

17 = 5 + 12 = 17

? = 17 + 14 = 31

47 = 31 + 16 = 47

65 = 47 + 18 = 65

The second sequence(even places):

2, 4, 6, 8

The pattern follow:

+ 2, + 2, + 2, + 2, ...

4 = 2 + 2 = 4

6 = 4 + 2 = 6

8 = 6 + 2 = 8

∴ The missing number (?) = 31
