Write the recursive formula for the geometric sequence.

a1 = -2 a2 = 8 a3 = -32

a. an = -4 an-1

b. an = -2 an-1

c. an = -2 • an-1

d. an = -4 • an-1

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
