<h2>Third choice. </h2><h2>0</h2>Step-by-step explanation:
The given sequence is
We need to only place the integer that can logically replace the underscore. To do that, we need an integer between -1.5 and 2.3.
As you can observe, -2 and -1 1/3 can't be the answer because -2 is not in the interval and -1 1/3 is not an integer.
The zero is the only option that fits, because is an integer and it's between -1.5 and 2.3.
Therefore, the third choice is the right answer.

Step-by-step explanation:
X^4 - 10X^2 + 9 =0 This factors. It just looks odd.
(x^2 - 1)(x^2 - 9) = 0
x^2 - 1 = (x + 1)(x - 1) = 0
x = 1 and x = - 1
x^2 - 9 = (x + 3)(x - 3) = 0
x = 3
x = -3
The correct answer is C (third one down).
