Question

find missing word .
give reason for your answer

Answer 1

it's like (27-13) = 14
so 14 +2 = 16

(37-23) = 14
14+2 = 16

SO (91-45) = 46

46 +2 = 48

Answer 2

There can be several answers:

First case

You see 13 and 23 form the first two numbers

13 = 1+3=4

and 23=2+3=5

So combine 13 and 23 to get 45

In the right side:

2+7=9

3+7=10

now 10=1+0=1

So this gives 91

In the middle 16=1+6=7

16=1+6=7

So combine them to get 77.

77 is the first answer

Second case

See the digits in the left and right

13 and 27

27-13 gives 14

14+2 gives 16

So next: 37-23=14

and 14+2=16

91-45=46

so 46+2=48

most probable answer

Hope it helps.
