Aurora is planning to participate in an event at her school's field day that requires her to complete tasks at various stations
Usimov [2.4K]

Step-by-step explanation:

an arithmetic sequence is a sequence of terms, where every term is created by adding a certain constant to the previous term.

a geometric sequence is when every term is created by multiplying the previous term by a certain constant.

the x coordinate serves as "n" counter of the terms in the sequence.

and the y coordinate is the actual sequence term of that "n".

so, we have

a1 = 4

a2 = 8

a3 = 16

a4 = 32

A)

I think, now it is obvious : the sequence is built by multiplying the previous term by 2.

and this is therefore a geometric sequence.

B)

a2 = a1 × 2 = 4×2 = 8 minutes

a3 = a2 × 2 = a1 × 2 × 2 = 4 × 2 × 2 = 4 × 2² = 16 minutes

a4 = a3 × 2 = 16 × 2 = 32 minutes

a5 = a4 × 2 = 32 × 2 = 64 minutes

C)

based on B we see

an = an-1 × 2 = a1 × 2^(n-1) = 4 × 2^(n-1) = 2² × 2^(n-1) =

= 2^(n+1) minutes

therefore

a8 = 2^(n+1) = 2⁹ = 512 minutes
