I found some online number puzzle as below:
My guess was 436 (go up by 118 again, as the left & right go up by 1) but apparently it was incorrect. I cannot see any other patterns, any ideas?

One plausible answer is
476 because it's the left-hand number cubed minus the right-hand number squared.
But puzzles of this type always have multiple plausible answers, especially when there are only two examples given with answers, as in this case. Your answer, 436, is just as good as mine, in my opinion.
