The pattern follows: subtract the square of digit sum from the previous number. 10 - (1+0)² = 10 - 1 = 9, but shows 11. Let me recalculate: 10 → 10-1²=9 (not 11). Actually the pattern seems to be: 10→11 (add 1), 11→19 (11+8), 19→1019 (19+1000), so 1019→2350 (1019+1331). The difference increases: 1, 8, 1000, 1331... Wait, 2350-1019=1331 which is 11³. The pattern is adding cubes: 1³=1 to 10 gives 11, 2³=8 to 11 gives 19, 10³=1000 to 19 gives 1019, 11³=1331 to 1019 gives 2350.
