Answer:
a(4) = 15/4
Step-by-step explanation:
Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.
Thus, the geometric sequence formula specific to this case is
a(n) = 30(1/:2)^(n-1).
What is the fourth term? Let n = 4,
a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,
a(4) = 15/4.
Answer:
f = 3
Step-by-step explanation:
8 = 2f + 2
-2 -2
6 = 2f
/2 /2
3 = f
1×5 or 5×1 would be a factual of it
1. Subtract 6 from both sides now you would get..
2z=-10
Now divide each side by 2z and you get
z= -5
So the answer is -5
