The first three terms of a geometric sequence are shown below. x+3,-2x2-6x,4x3+ what is the eighth term of the sequence?

You have first three terms of the geometrical sequence:

You should know how the terms of geometrical sequence are formed:

where r is a ratio of geometrical sequence.

Comparing first three given terms, you can conclude that and . Then

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
