ISF YOU GET IT RIGHT I WILL NAME YOU BRAINLIST. A sequence can be generated using a, = 60(1/2)"-1. What are the first four terms in the sequence? A 60, 120, 240, 480 B 60, 30, 15, 7.5 C С 60, 120, 180, 240 60, 90, 135, 202.5 ОА B. D​

C

Step-by-step explanation:

You just plug in the # in the sequence you wanna find,

n=1

60((1)/(2))^(1-1) = 60  (1st term)

--

n=2

60((1)/(2))^(2-1) = 30 (2nd term)

--

n=3

60((1)/(2))^(3-1) = 15 (3rd term)

--

n=4

60((1)/(2))^(4-1) = 7.5 (4th term)

step-by-step explanation: 2

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
