Answer 1

Answer:

75

Step-by-step explanation:

To find the missing number

Given 57, 72, 98 21, 34, x, 123

In this, we get

57+72=129; 98+21=119; 34+75=109

Finally, we get x value is 75.

Answer 2

Answer:

Value of X = 75

Step-by-step explanation:

Given are 57,72,98,21,34,X,123

To find X value:

If we add 57 and 72 we will get 129

and if we add 98 and 21 we will get 119 by this we

can observe that the sum is decreasing by 10.So if we

add 34 and X we will get 109 as a answer. So if we

add 34 to 75 we will get 109.

57 + 72 = 129

98 + 21 = 119

34 + X = 109

X = 109 - 34

X = 75

therefore, value of X = 75
