1 A central angle must have its vertex at...
A on the circumference of a circle
B) outside a circle
anywhere in a circle
D the center of a circle

the answer is D. the center of a circle

see explanation

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

range is infinite on both x and y axis positive and negative
