I'm stuck on this question: find the 3 consecutive numbers whose sum is 438. can someone take me through it?

X + x+1 + x+2 = 438
3x = 438 -3
3x = 435
x = 145
So the three consecutive numbers are
145
146
147

Answer is a.  6 x plus 16 equals 82  6x+16=82======if you let  be  the first odd integer, then the three  consecutive odd integers are    because adding two to an odd integer still gets an odd number.for example, 1 + 2 = 371 + 2 = 7353 + 2 = 55all odd, so adding 2 gets the next consecutive odd integer."the first" means  "two times the second" means  you can distribute and it becomes  "three times the third" means  you can distribute and it becomes  if you sum all these expressions up, they should equal 82.
