Arithmetic sequence

The difference between two terms in an arithmetic sequence is called ___________________.

• Formula

• Common Ratio

• Common Difference

• Common Factor

What is a₁ in the following sequence?

-6, -14, -22, -30, ...

• -6

• -14

• -22

• -30

• previous term

• first term

• common difference

• the sequence contains only negative numbers

Given the sequence -5, -15, -25, -35..., which recursive formula describes it?

Given the sequence 11, 15, 19, 23..., which recursive formula describes it?

We will start with the explicit formula. Given the following sequence, state the first term and common difference.

Example 1:          4, 7, 10, 13, 16, …

Now, write the explicit formula for the given sequence.

Example 1:          4, 7, 10, 13, 16, …

Now, find the term BEFORE term 1 (term 0).

Example 1:          4, 7, 10, 13, 16, …

•  1

•  4

•  7

•  0

Which equation matches the following sequence? 4, 7, 10, 13

Write the equation that would match the following sequence: 100, 90, 80, 70...
