<u>Arithmetic Sequences </u>
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:

Answer: D
Answer:
x = -
Step-by-step explanation:
-x - 1 =
add 1 to both sides:
-x =
multiply both sides by 4:
-3x =
divide both sides by -3:
x = -
