Răspuns :
Cum numerele sunt consecutive,le voi nota a=primul numar si a+1=al doilea numar
a+a+1=646
2a+1=646
2a=645
a=322,5
a+1=323,5
a+a+1=646
2a+1=646
2a=645
a=322,5
a+1=323,5
a=primul numar
a+1=al doilea numar
a+a+1=646
2a+1=646 |-1
2a=645 |:2
a=322,5 -primul nr
a+1=322,5+1=323,5 -al doilea nr
Succes!
a+1=al doilea numar
a+a+1=646
2a+1=646 |-1
2a=645 |:2
a=322,5 -primul nr
a+1=322,5+1=323,5 -al doilea nr
Succes!
