Translate the following: The sum of three consecutive even integers is less than 25.

x + y + z < 25

1x + 2x + 3x < 25

x + (x+1) + (x+2) < 25

x + (x+2) + (x+4) < 25

Translate the following: The sum of three consecutive odd integers is less than 40.

x + y + z < 40

1x + 2x + 3x < 40

x + (x+1) + (x+2) < 40

x + (x+2) + (x+4) < 40

Translate the following: The sum of three consecutive even integers is less than 25.

Your answer would be
x + (x+2) + (x+4) < 25,
assuming in this case that x is an even integer.

The sum of three consecutive even integers less than 25 is :
x + (x + 2) + (x + 4) < 25

The sum of three consecutive odd integers less than 40 is :
x + (x + 2) + (x + 4) < 40

(2n-2)+2n+(2n+2)<25 so 6n<25 and n<=4

(2n-1)+(2n+1)+(2n+3)<40
6n<37 and n<=6
for n=6 we have
11+13+15=39<40
