Answer: z
=
0.375
Step-by-step explanation:
She read 5.5 books per month x
y = -2(x-4)2-6
= -4(x-4) - 6
= -4x + 16 -6
y = 10- 4x
now if x is positive, x >= 0
then max value of y will be when x will nr minimum
so max y = 10- 4×0 = 10
so y = 10 at x =0 for x >=0
if x < 0 then
y will be increasing as x gets increase towards more negative. so max of y will be decided when x reaches to max negative.
0.16 as a fraction becomes 16/100. This can be simplified to 4/25.
None of those are the right answer, though 1/6 as a decimal is 0.16666666... (the 6s repeat forever) so option C is what they're looking for.

Common ratio is -2
next 3 terms :
32 * -2 = -64
-64 * -2 = 128
128 * -2 = -256
answer is D
