Question

the sum of three consecutive numbersis 72. what are the smallest of these numbers

Answer 1

X

X+1

X+2

_______

3X + 3 = 72

 

3X = 69

 

X = 23, the smallest number

 

 

The average of three consecutive numbers will always be the middle number

 

(3X+3)/3 = X+1

 

Therefore, you can always find the middle number by simply dividing the sum by 3 and then add 1 and subtract 1

 

72/3 = 24

 

so my numbers are 23, 24, 25
