Resposta:$+10,+6,0,-19,-14,-16,+15,+6,-21,-2,-27,+16,-10,16,0$

Explicação passo a passo:

$-7+17=\\+10$

$+16-10=+6\\-1+1=0\\-3-16=-19\\+8-22=-14\\+5-21=-16\\+1+14=+15\\-23+29=+6\\-93+72=-21$

$-20+7+11=-20+18=-2\\-15-5-7=-20-7=-27\\14+29-11-16=43-27=16\\29+33-72=62-72=-10\\35-100-101+182=217-201=16\\26-42+17+25-26=68-68=0$
