Consecutive integers---->system%28x=1st+number%2Cx%2B1=2nd%2Cx%2B2=3rd%2CTotal=40%29
x%2Bx%2B2=40,condition 1----> Sum of Smallest & Largest (1st & 3rd)
2x=40-2=38
cross%282%29x%2Fcross%282%29=cross%2838%2919%2Fcross2%29
x=19, Smallest
19%2B1=20, 2nd
19%2B2=21, Largest
Check, go back condition
Sum is 40:
19%2B21=40
40=40
