Answer 1

1st is a geometric sequence with common ratio, r = 3. And first term is 6

general formula for a term in the sequence is An = A1 times r^(n-1)

A10 = A1(r^9) = 6(3^9) = 118,098

2nd is G_d knows what. Although someone lesser out there might figure it out, aside from Allah, Jehovah, Jesus, Buddha, Brahma, Yeshiva,Krishna, the Sun Goddess or "the Force" Prayer might be the best method to figure it out. Science has its limits.

Answer 2

The first one is a geometric sequence and you should easily see the ratio and be able to answer the questions.

The 2nd one is not obvious. Are you sure you copied it correctly?
