Rosita is writing an explicit function for the geometric sequence:
80, 40, 20, 10,...
She comes up with t(n) = 160(1/2)^n
What domain should Rosita use for T so it generates the sequence?
Choose 1 answer
A: n ā‰„ 0 where n is an integer
B: n ā‰„ 0 where n is any number
C: n ā‰„ 1 where n is an integer
D: n ā‰„ 1 where n is any number

Respuesta :

Answer:

C- where n (greater than or equal to ) 1

Step-by-step explanation:

C- where n (greater than or equal to ) 1

Because in that sequence 0 doesn't make sense since 160 * 1/2 = 80 ^ 0 = 1. Doesn't make sense since there's no "1" in that sequence.

It's not "any number" because It can't be negative nor a decimal.

So, C.
