Answer 2

Answer:

5

8 2

7 9 -5

5 9 9 x

The missing number is -19

Step-by-step explanation:

Here,

5

8 2

7 9 -5

5 9 9 x

Where x is the unknown number

In the first row, to get 5,we have to add the numbers and in the second row between which 5 is placed and divide the result by 2.

That is ,( 8+2) ÷ 2 = 10/2 = 5

Repeat the same, for the other rows

To get 8 in second row, we have to add 7 and 9 in the third row and divide it by 2

That is, (7+9)÷ 2 = 16/2 = 8

And similarly, to get 2,

(9+(-5)) ÷ 2 =( 9-5 ) ÷ 2 = 4/2 =2

Now, consider the third row, the same pattern is followed

(5+9) ÷ 2= 14/2 = 7

(9+9) ÷ 2 = 18/2 = 9

So,

To get -5,

We have to add 9 with x and divide the result by 2

That is,

(9+x) ÷ 2 = -5

9+x = -5*2

9+x = -10

x = -10-9

x = -19

So, the missing number is -19
