A way to work this out is figure out how many possible digits can go in each place value position (units, tens, hundreds) and multiply these together. Since there are 2 possible digits that can go in each position and there are three positions, you would go: 2 x 2 x 2 = 8

Two positive integers whose sum is 14 includes 6 and 8

The two consecutive positive integers whose product is 380 are 19 x 20.

Those three odd integers are 43, 45, and 47.

117/3 = 39, so the three consective odd integers whose sum is 117 are 37, 39, and 41.

The integers are 99, 100 and 101. There is also a set of consecutive even integers whose sum is 300. That set is 98, 100 and 102.
