Ageometric sequence has these terms: a1 = 8, a2 = 20, az = 50, and a4 = 125.
which formula can be used to find an?
o a. an = 8 + 12 (n-1)
ob. an = 8+ (n - 1)
oc. an = 8. 121-1
od. an =
o e. on = "

= 8

Step-by-step explanation:

The n th term of a geometric sequence is

= a

where a is the first term and r the common ratio

Here a = 8 and r = = 2.5, thus

= 8

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.
