Question

afla 3 numere consecutive stiind ca adunandule cu triplul sumei lor se optine rezultatul 528

Answer 1

(a+b+c)+((a+b+c)*3)=528
b=a+1
c=a+2

a+a+1+a+2=x
x+x*3=582
4x=582
x=582:4
x=132

a+a+1+a+2=132
3a+3=132
3a=132-3
3a=129
a=129:3
a=43

b=43+1
b=44
c=43+2
c=45

(43+44+45)+((43+44+45)*3)=
=132+(132*3)
=132+396
=528
