HELP MEEE

A value in a sequence is 2 times the previous value, like this: {8,16,32,64}.
How would this sequence be represented as a recursive equation?

A a1=8 and an=2a1
B a1=8 and an=2n
C a1=8 and an=a1+2n
D a1=8 and an=2an−1

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

i just took the test, the correct answer is .. 31.5 in.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
