Two consecutive integers whose sum is 19 is 10 & 9; 10+9 = 19.
They are 8+9 = 17
The numbers are -5 and -4.
They are -9 and -8.
The sum of any two consecutive integers is odd. Try it out. 3 + 4 = 7 4 + 5 = 9 If it works for those, it works for all of them.
The numbers are 9 and 10.
The integers are 7, 8 and 9.
The sum of even integers cannot end with 9. why not
4 and 5
9 and 11
9 and 11.
