Răspuns:

a:11=19

11*19=209

11*19+1=210

11*19+2=211

11*19+3=212

11*19+4=213

11*19+5=214

11*19+6=215

11*19+7=216

11*19+8=217

11*19+9=218

11*19+10=219

a={209,210,211,212,213,214,215,216,217,218,219}

2++09+210+211+212+213+214+215+215+216+217+218+219=209+210+211+212+213+214++215+216+217+218+219=4454(Nu am mai facut calculul aici, l-am facut pe calculator si l-am transcris)=>Rezultatul este 4454.
