Aí está um bom desafio para os alunos e alunas do 1° ano A!
Leiam atenciosamente o desafio, compreenda, busque estratégias para resolvê-lo e mostre porque a resposta certa é o item d.
Sua resposta deve ser postada aqui no blog, pensem muito e bom estudo!!
DESAFIO: 
(FUVEST/01) Uma progressão aritmética e uma progressão geométrica têm, ambas, o primeiro termo igual a 4, sendo que os seus terceiros termos são estritamente positivos e coincidem. Sabe-se ainda que o segundo termo da progressão aritmética excede o segundo termo da progressão geométrica em 2. Então, o terceiro termo das progressões é:
a) 10
b) 12
c) 14
d) 16
e) 18
