I would guess 765.
345, 555
3+2=5
4+1=5
5+0=5
Answers add up to 555.
Therefore, using the same idea...
5+2=7
5+1=6
5+0=5
Answers add up to 765.

2+3=53+5=85+8=1313+21=3333 is the next number in this pattern. This pattern is called a Fibonacci.
33
512 squared
27= 3364=43125=53so next number will be 63 = 216
If you mean: 9, 19, 39, 69 then the next number in the sequence is 109
The rule of this pattern is -2 + 6 +4 so the next number would be 16.
