I think this is a geometric sequence...
d alam ko na ang sagot tssk na mali yata yung guro namin sa pag sulat imbis 8 naging 8
there is one lost in this sequence, and that is 2^3=8. I realized that 9 is wrong here because if the sequence is "Cubic Sequence" then 9 is not a cubic number...
yun nga eh wrong pala ng pag bigay yung teacher hahhaha thanks po
