Consider the arithmetic sequence:
prisoha [69]

Answer:

<em>Answer: D</em>

Step-by-step explanation:

<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:

a_n=a_1+(n-1)r

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:

a_n=10+(n-1)2

Operating:

a_n=10+2n-2

a_n=8+2n

Answer: D
