Answer 2

Missing number (?) = 57

Step-by-step explanation:

The given series are:

1, 101, 15, 4, 29, - 93, 43, - 190, ?​

To find, the value of missing number in the given series (?) =

The given series contains two series.

First series (Odd places):

1, 15, 29,  43, ?​

The pattern follow:

+ 14, + 14, + 14, + 14, ......

15 = 1 + 14 = 15

29 = 15 + 14 = 29

43 = 29 + 14 = 43

Similarly,

? = 43 + 14 = 57

Second series (even places):

101, 4, - 93, - 190

The pattern follow:

- 97,  - 97,  - 97, - 97, .........

4 = 104 - 97 = 4

- 93 = 4 - 97 = - 93

- 190 = - 93 - 97 = - 190

∴ Missing number (?) = 57
