The 1st integer is x
The numbers go odd, even, odd, even, etc.
so, the next odd number is x+%2B+2
and thr next odd integer is x+%2B+4
The sum is x+%2B+x+%2B+2+%2B+x+%2B+4+=+3x+%2B+6 answer
to check: suppose x+=+7
x+%2B+2+=+9
x+%2B+4+=+11
7+%2B+9+%2B+11+=+27
and
3x+%2B+6+=+3%2A7+%2B+6
21+%2B+6+=+27
OK
