Easy Arithmetic

Find three consecutive odd cubes whose sum is a four (decimal) digit
number with identical digits.

I found four candidates, (the four digit numbers being
1197,2403,4257,6903).
What am I missing?

I found the same candidates. Are we doing something wrong or did davar55 word the problem wrong?

Maybe by "consecutive" he meant distinct.

I did find the same candidates, but changing the problem to 3 consecutive squares I get 5555 = 41^2+43^2+45^2

That's quite a coincidence.
Must be what he meant. Well spotted!

Mea culpa. I did mean three consecutive odd squares.
There's something to be said for repeating a preview before posting.
And on such a simply stated problem.
:blush:
