1)A sequence has a first term of 24 and every other term is one half of the previous term.

a)Write the first four terms of the sequence.

b)Find a recursive formula that defines this sequence.

c)Find an explicit formula that defines this sequence. This will be discussed later, but you could use the geometric form tn=ar(n-1) where a is the first term, r is the common ratio and n is the number of terms.

d)Find t6 and t8.

**bobpursley**, Wednesday, August 8, 2012 at 7:14pmEither you are lost, or are looking for someone to give you answers. I will assume the former for now:

a) 24, 12, 6,3, ...

b) a_{n}=a_{n-1}*1/2

c. tn=24*(1/2)^{n}

t6= 24*(1/2)^6=24/64
