How about: 17+23 = 40 as one example
-37
40
-42
None that are all odd numbers. But, there are two sets of three consecutive numbers containing a mix of even/odd that add up to 120. They are 39, 40 and 41 and also 38, 40 and 42.
They are: 3+37 = 40
They are 40 and 40
391
-37
50 squared = 2500 40 squared = 1600 add these two together to get 4100 so your answer is 50 and 40
40
The factor pairs of 4 are (4,1) and (2,2) Neither of them add up to 40.

70
They are: 3+37 = 40
50 and 5, 51 and 4, 40 and 15........
Those two numbers would be 80 and 40. 80*40=3200 80+40=120
