U can find the common ratio by dividing the 2nd term by the first term
r = -9/3 = -3
an = a1 * r^(n - 1)
a1 = 1st term = 3
r = common difference = -3
now sub
an = 3 * -3^(n - 1) <== ur formula
domain : all integers where n > = 1 <==

Answer:
Major arcs are greater than 180 degrees
Step-by-step explanation:
See photo attached for example.
The answer is: "squares".
1. Therefore, the complete sentence is:
"<span>A difference of two squares is an expression that contains two perfect squares, with one subtracted from the other".
</span>
2. It has the following form:
a²-b²
3. You can factor the expression above as below:
(a-b)(a+b)
4. For example:
x²-4 can be written as x²-2², then it can be factor as following:
x²-2²=(x-2)(x+2)
