Ja us podeu imaginar que els components de la
comissió no ens inventem tots els problemes, sinó que consultem
publicacions. Com que ara en volem posar un que hem llegit a The
United Kingdom Mathematics Trust Yearbook...

The first
and second terms of a sequence are added to make the third term:
first term + second term = third term Adjacent odd-numbered terms are added to make the next even-numbered term, for example first term + third term = fourth term and third term + fifth term = sixth term Likewise, adjacent even-numbered terms are added to make the next odd-numberes term, for example, second term + fourth term = fifth term. Given that the seventh term equals the eight term, what is the value of the sixth term? Per enviar
