In order to solve this problem, you must divide 30 beads by 5 beads to get 6 pairs of purple beads. Then multiple 6 by 2 to get 12 white beads.
In ratio form, this can look like 30:12

Mathematics

Part A: Geometric Sequence

Part B: $a_1 = 4, a_n = 2a_{n-1}$

Part C: a₈ = 512

Step-by-step explanation:

When we find the common ratio between the y-values (x-values are n inputs), we should see that we get r = 2. That means we have a geometric sequence.

Because we have a geometric sequence, our recursive formula is: $a_1, a_n=ra_{n-1}$ . Simply plug in our known variables:

$a_1 = 4, a_n = 2a_{n-1}$

Now we need to find what y is when x = 8, so (I used explicit formula):

$a_8 = 4(2)^{8-1}$

a_8=4(128)

a₈ = 512
