Sequences
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(n1) where a is the first term, r is the common ratio and n is the number of terms.
d)Find t6 and t8.

Either 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_{n1}*1/2
c. tn=24*(1/2)^{n}
t6= 24*(1/2)^6=24/64
