Question

What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of -8?

Answer 1

These are the choices:

an = 2(-8)n - 1; all integers where n ≥ 1

an = 2(-8)n - 1; all integers where n ≥ 0

an = 2(-4)n - 1; all integers where n ≥ 0

an = 2(-4)n - 1; all integers where n ≥ 1

Answer 2

MEDAL AND FAN :)

Answer 3

@Vocaloid I know im annoying cuz i almost always ask u for help but ur always right and i actually learn stuff when u answer rather than those who just give me answers

Answer 4

@pink.1d you're not annoying, don't apologize

just hold on a sec

Answer 5

I think its the third one but my friend said im wrong

Answer 6

okie:)

Answer 7

ahah, your friend was right, I'm sorry to say

you're very close, though!

Answer 8

alright, let me show you why the 3rd answer isn't right

if we start with n = 0, then the first term is 2(-4)(n) - 1, where n = 0. that means that the first term is -1, which doesn't match with the problem

Answer 9

oopps wow sometimes im so stupid

Answer 10

ok now i think it is

Answer 11

fourth one duh

Answer 12

yup

Answer 13

thanks for helping me when i became stupid:) lol

Answer 14

What are the explicit equation and domain for an arithmetic sequence with a first term of 7 and a second term of 3? (5 points)

an = 7 - 4(n - 1); all integers where n ≥ 1

an = 7 - 4(n - 1); all integers where n ≥ 0

an = 7 - 3(n - 1); all integers where n ≥ 1

an = 5 - 3(n - 1); all integers where n ≥ 0

Answer 15

@Vocaloid i think its

Answer 16

first one

Answer 17

also i have to ask u something

Answer 18

since you are more experienced at life , is it bad to listen to music while u do school work?

Answer 19

my mom keeps saying i will be a stupidhead and the info will go in one ear and out the other

Answer 20

@pink.1d yes, your answer is correct

Hm, as for the music question, it really depends on the person. Studies have shown that most people perform worse when music is playing in the background with the exception of classical music.

Answer 21

ya thats what i found out

Answer 22
