Draguta problema, insa cred ca e mai potrivita pentru sectiunea de matematica distractiva .
Exista o corespondenta intre numerele de pe linia \( k+1 \) si linia \( k \) , asa cum am aratat am jos ...
\( \begin{array}{cccccccccccc}
1 \\\\\\\\
1\ \overline{\underline{\left| 1\right|}} & \mbox{pe linia 1 se afla \underline{un} 1}\\\\\\\\
2\ \overline{\underline{\left| 1\right|}} & \mbox{ pe linia 2 se afla \underline{doi} de 1}\\\\\\\\
1\ \overline{\underline{\left| 1\right|}}\ \ 1\ \overline{\underline{\left| 2\right|}} & \mbox{ pe linia 3 se afla \underline{un} 1 si \underline{un} 2} \\\\\\\\
