Question

Find three consecutive even numbers whose sum is 234

Answer 1

You know that consecutive means line Wise. so.

(x) + (x+2) + (x+4) = 234

by opening brackets

x  + x + 2 + x + 4 = 234

x + x + x + 2 + 4 = 234

3x + 6 = 234

3x = 234 - 6

3x = 228

x = 228/3

x = 76

so, First number = x  

= 76 

Second number = x + 2

= 76 + 2

= 78

Third number = x + 4
= 76 + 4
= 80

you can see , that. 76 + 78 + 80

= 234

so, three consecutive numbers are 76, 78 and 79.

Answer 2

consecutive evn numbers = x , x+2 , x+4
statement form = x + (x+2) +(x+4) = 234
x + (x+2) +(x+4) = 234
x+x+2+x+4=234
3x+6=234
3x=234-6
3x=228
x=228/3
x=76
x+2 = 76+2 = 78
x+4 = 76+4 = 80

so the three consecutive numbers that sum up to 234 are - 76,78,80
