Let an denote the nth term of a geometric sequence. Let a0=256 and an+1=0.5an . Part A

Write an explicit formula for this sequence.

an=

Part B

To the nearest whole number, what is the sum of the first 25 terms?

-1

step-by-step explanation:

i believe the answer is y=0.25x+-3

[ie

we know that

major arc is defined as the bigger arc connecting two points on the edge of a circle. measure of major arc is always more than ° or π radian

in this problem

the mayor arc is bac

find the ratio of the measure of the major arc to the measure of the minor arc

therefore

the answer is the option
