Question

Given the geometric sequence where a1 = 4 and the common ratio is 3, what is the domain for n?

A) All integers where n ≥ 1
B) All integers where > 1
C) All integers where n ≥ 4
D) All real numbers

Answer 1

The answer is A. All integers where n > 1

Explanation:

The domian for n is restricted and cannot be less than 1 and the domain is the x value while 4 would be a y value.

Answer 2

The correct option is A.

Explanation:

According to statement a1 = 4 and r = 3. This shows that r is greater than 1.

If r is greater than 1 than it includes integers greater than 1 or equal to 1. It does not include all the real numbers because real numbers include negative numbers also.

If starting value is 4,if we put n=0, then we get 4, but if we put a negative value than we would get a number which is not a part of our sequence. Thus the correct option is All integers where n ≥ 1....
