Well, let's see:
-- Since their sum is 762, their average must be 762/4 = 190.5
-- Since they're consecutive, the first two pretty much have to be
less than 190.5 and the last two have to be more than 190.5 .
-- Now we can see how they have to line up: 189, 190, 191, and 192 .
The fourth one is 192 .
