What is the recursive rule for =2n+11?

Step-by-step explanation:

The given equation is

It's important to know that a recursive formula shows two important characteristics.

So, in this case, we first need to find the first term of the given sequence, that is, when

So, the possible answers are the first and third choices.

Now, the following term would be when

As you can see, the second term is 2 units greater than the first term. That means the right answer is the third choice, because it has a positive term of two units.

Let's try for

Therefore, the answer is

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
