We have a geometric sequence----------- > <span>{-4, 12, -36, ...}
</span><span>
the formula is a(r)^(n-1)
a------------- >a is the first term------------ > -4
r--------------- > </span><span>is the common ratio------- > 12/(-4)=(-36/12)=-3
n--------------- > is the number of terms
</span>The fifth term is -4[(-3)^(5-1)]=-4[(81]=-324
the answer is -324
f(x) is a linear function, so both the domain and the range are the set of real numbers.
Hmm...I tried to divide 29 by 14, and I got 2.07142857143.... Does it let you round the decimal..?
Answer:
I'm pretty sure the answer is a.
