The first four terms of a sequence are shown on the graph below. On a coordinate plane, points are at (1, negative 1), (2, 8), (
Masja [62]

Answer:

  • The next term of the sequence is represented by the point (5, –64)

Step-by-step explanation:

<u>Note:</u> <em>The first point should be (1, - 4)</em>

According to the points, the sequence is:

  • t₁ = - 4, t₂ = 8, t₃ = - 16, t₄ = 32

or

  • - 4, 8, - 16, 32, ...

We can observe it is a geometric sequence with common ratio of - 2, as:

  • r = 32/ - 16 = - 16/8 = 8/ - 4 = - 2

The following term is:

  • t₅ = t₄*r = 32*(- 2) = - 64

The coordinates of same term are:

  • (5, - 64)

As we see the correct answer choice is D.
