-78
We subtract 1, then 3, then 5, then 7
Then subtract 9,11,13,15,17
-21 -11 = -33
-33 -13 = -46
-46 -15 = -61
-61 -17 = -78
3, 2, -1, -6, -13, -22, -33, -46, -61, -78
1,143 : 1,100
1,149 : 1,100
5600
It seems to be multiplying by 2 each harvest, 350*2=700, 700*2=1400, and 1400*2=2800, so logically, the next harvest will be 2800*2, which is 5600.
