Finding Arithmetic Sequences

These are terms between any two non-consecutive terms of an arithmetic sequence.

• Arithmetic Means

• Arithmetic Sequences

• Arithmetic Series

• Arithmetic Pattern

A theater has 32 rows of seats. If there are 26 seats in the 1st row, 30 in the 2nd, 34 in the 3rd, and so on, how many seats are there in all? Assume the pattern continues.

• 2,791 seats

• 2,803 seats

• 2,816 seats

• 2.829 seats

It is the sum of definite number of terms of an arithmetic sequence

Which of the following is an example of an arithmetic sequence?

• 4, 8, 16, 32, 64

• 1, 2, 4, 7, 11

• 15, 13, 11, 9, 7

• 3, 6, 12, 24, 48

The first three terms of an arithmetic sequence are as follows

13, 19, 25, ​ (a)   , (b)  

What are the next two terms of the sequence?

• 31

• 37

• 36

• 30

• 32

• 38

• 29

Which of the following is the correct formula in finding the nth term of an arithmetic sequence?

• a_n = a₁ + (n - 1)d

• a_n = a₁ + (n + 1)d

• a_n = a₁ - (n - 1)d

• a_n = a₁ + -(n + 1)d

The difference between two terms

in an arithmetic sequence

is called a ​ ​ (a)   ​

• common difference

• Formula

• Common Ratio

• Common Factor

If the sequence 6, 11, 16, 21 continues, what will be the 9^th term?

Determine whether the sequence is arithmetic, geometric, or neither:
-4, 1, 6, 11, ...

• arithmetic

• geometric

• neither

What is a₁?

• the number you multiply to get from one term to the next

• the term you are trying to find 

• the number you add to get from one term to the next

• the first term
