Answer 1

Answer:

5

Step-by-step explanation:

let the 3rd no be x

the sum of no =6+7+x=13+x

6=(13+x)/13

18=13+x

x=5

Answer 2

Answer:

The third number is five.

Let the third number be x

The sum of three numbers = 6 + 7 + x = 13 + x

Average of three numbers = Sum of three number / 3

= > 6 = ( 13 + x ) / 3

= > 18 = 13 + x

= > x = 5

Third number = 5
