Question

suma a cinci nr naturale consecutive este 615 afla nr

Answer 1

a=cel mai mic nr.
a+1=urmatorul numar
a+2=umratorul numar si asa mai departe...
a+a+1+a+2+a+3+a+4=615
a+a+a+a+a+1+2+3+4=615
5a+10=615/-10
5a=605/:5
a=121

Answer 2

a+b+c+d+e=615
a,b,c,d,e=numere consecutive
a,b,c,d,e=?
a=1segment
b=1segment+1
c=1segment+1+1
d=1segment+1+1+1
e=1segment+1+1+1+1
615-10=605(5segmente.egale)
605÷5=121(a)
121+1=122(b)
121+1+1=123(c)
121+1+1+1=124(d)
121+1+1+1+1=125(e)
V:121+122+123+124+125=615
