In this sequence, a₁ equals -1. 

The difference between each term is +3, so the coefficient for n will be 3.

In the sequence, a₂ equals 2. The following equation will fit this sequence, and will be your answer:

a_n = -1 + 3(n - 1)

Proof:
a_1 = -1 + 3(1 - 1) = -1 + 3(0) = -1

a_2 = -1 + 3(2 - 1) = -1 + 3(1) = -1 + 3 = 2

For which rational expression is –2 an excluded value of x?
Kipish [7]

Answer:

option a is the answer

Step-by-step explanation:

put the value of x in each expression as x = -2

you'll see that in option a the expression becomes

\frac{x - 3}{ {x}^{2}  - 4}   =   \frac{ - 2 - 3}{ {( - 2)}^{2}  - 4}  \\  =  \frac{ - 5}{4 - 4} \\  =   \frac{ - 5}{0}

which is not defined. hence -2 is excluded value
