Question

The sum of three consecutive EVEN integers is 42. What are the integers? (Name all three)

Answer 1

42/3 = 14
So 14 + 14 + 14 = 42
14 - 2 = 12
14 + 2 = 16

Thus 12 + 14 + 16 = 42

Answer 2

name them as
a,b,c
so a=2k
b=2(k+1)=2k+2
c=2(k+2)=2k+4
now a+b+c=42

Answer 3

2k + 2k+2 +2k+4=42

6k+6=42 --> k=6

so a=2*6
b=2*6+2=14
c=2*6+4=16

Answer 4

another way to solve this is:
x + x + 2 + x + 4 = 42
3x + 6 = 42
3x = 36
x = 12
12, 14, 16.
