Step-by-step explanation:
2+1+7+4=14
red marbles are 4/14
154cm squared this is the only right answer
-4x +12 -12 = -4 -12
-4x = -16
x = 4
Answer:
8*2^(n-1)
Step-by-step explanation:
This is a geometric sequence since we multiply from the previous term.
a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.
The first term is 8, so we have
a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)
If you do the division, you would end up with the answer letter D, 1/8.
