what is the iterative rule for this sequence?

Step-by-step explanation:

Givens

The formula to find the iterative rule of an arithmetic sequence is

Where and , replacing these values, we have

Therefore, the right answer is the first choice:

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
