Question

The average of 7 consecutive odd number is 36 what is the difference between the highest to lowest number

Answer 1

Step-by-step explanation:

let the lowest number be 'x'

let the highest number be 'x+12'

let the 7 consecutive odd numbers be x, x+2, x+4, x+6, x+8, x+10, x+12

The Average of 7 Consecutive Odd numbers = 36

x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)+(x+12)/7 = 36

7x+42/7 = 36

7x+42 = 36×7 = 252

7x = 252-42 = 210

x = 210/7 = 30

Lowest number be 'x' = 30

Highest number be 'x+12' = 30+12 =42

Difference = 42-30=12
