234,510,133 si 11 ma.............................
media arirmetica a trei numere naturale consecutive este 186 Determinati numerele ....................................................................................................................................

Answer 1

ma: (39+13):2=52:2=26
ma: (72+81+102):3=255:3=85
ma: (234+510+133+11):4=888:4=222

(a+b+c):3=186
a+b+c=186*3
a+b+c=558
558-186
372
372-186=186 
186-186=0
