А. has cross-sectional shapes, taken parallel to a base, that are similar but not congruent to one another.
A. polygon
B. prism
C. pyramid
O D. cube

Option D.

Step-by-step explanation:

If Stefani slices the pyramid

Option A). parallel to the base through vertex, cross section will not be a trapezoid.

Option B). perpendicular to the base through the vertex, cross section will be a triangle.

Option C). parallel to the base but not through the vertex, cross section will be a rectangle.

Option D). Perpendicular to the base but not through the vertex, cross section will be a trapezoid.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
