Question

Given the arithmetic sequence an = 6 − 4(n + 2), what is the domain for n?

Answer 1

the given eqn can be written as 6-4n-8
=-2-4n
so domain is (-infinity,+infinity)
(since the above function satisfies for all n belongs to R

Answer 2

All integers where n ≥ 0

All integers where n ≤ 1

All integers where n ≥ 1

All real numbers

Answer 3

is it the first option?

Answer 4

no i think it as 4th one

Answer 5

thanks =)

Answer 6

Given the geometric sequence where a1 = 5 and the common ratio is −3, what is the domain for n?

All integers where n ≥ 0

All integers where n ≥ 1

All integers where n ≥ 5

All integers where ≤ 5

Answer 7

this is basically the same problem. i just can't seem to solve them accurately @thanooz

Answer 8

but where is 'n'??

Answer 9

Idk! =P thats why im asking. i don't how u can solve in that format

Answer 10

it doesn't give the equation

Answer 11

might be 2nd option is right....
