We know that even integers are 2 numbers apart
2, 4, 6, ...
since we know that, we know hat the next odd integer would be just 1 number apart, then the next odd integer would be:
2x+6+1
2x+7 ---> Next odd integer
Also, odd integers are 2 numbers apart, so the next odd integer would be 2x+7 plus 2:
2x+7+2
2x+9 ---> 2nd odd integer
