MEANS and its DEFINITION
Arithmetic Means RULE #02
This rule only applies if a particular sequence of terms has an even number of terms, we utilize this formula:
                d = an - a1 / n-1
Where d is the common difference,
an is the last term
a1 is the first term 
And n refers to the number of terms.

Even number
formula
Arithmetic Means RULE #02

In this example,
7, ?, ?, ?, ?, 22

If you add up all the terms, you'll see there are six. Six is an even number, thus you may use this formula to determine the missing means.

Arithmetic Means RULE #02
Substituting these digits, you will get the equation,
d = an - a1 / n-1
d = 22 - 7 / 6 - 1

eVEN number
formula
Arithmetic Means RULE #02

- First, substitute 22 to an since it’s the last term in the sequence.
- Next, substitute 7 to a1 since it’s the first term.
- Finally, substitute 6 to n since there are 6 terms in the sequence.

D = 22 - 7 / 6 - 1
THE NUMERATOR

SHOULD NOW
Arithmetic Means RULE #02

d = 22 - 7 / 6 - 1

eVEN number
formula
22 - 7
= 15

Arithmetic Means RULE #02

d = 22 - 7 / 6 - 1

eVEN number

denominator
solved
Arithmetic Means RULE #02

d = 22 - 7 / 6 - 1

eVEN number
formula
simplify
the fraction
15 ÷ 5
= 3
Arithmetic Means RULE #02
The second term is the common difference plus the first term added together; this process should be repeated until the sixth term:

7 + 3 = 10
10 + 3 =13
13 + 3 = 16
16 + 3 = 19

THE COMMON

Arithmetic Means RULE #02
Finally, Three plus nineteen equals twenty-two. Since 22 is the last term in the sequence, the sequence is clearly arithmetic due to its common difference.
even number
formula
THE SEQUENCE
SOLVED.
IS NOW
19 + 3 = 22
7, 10, 13, 16, 19, 22
