Answer 2

The missing number(?) = 89.

Step-by-step explanation:

We have,

To find, the missing number = ?

14  78  47

28  ?   42

79  37  63

The pattern follow row-wise,

The sum of first row = 139, The sum of second row = 159 and The sum of second row = 179

In first row,

14 + 74 + 47 = 139

In third row,

79 + 37 + 63 = 179

Similarly,

In second row,

The sum of second row = 159

28 + ? +  42  = 159

⇒ ? + 70 = 159

⇒ ? = 159 - 70 = 89

Hence, the missing number(?) = 89.
