Arithmetic Sequences

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

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

State the common difference:

Example 2: 21, 19, 17, 15, …

(a)  

Write and explicit rule to model the following sequence:

Find the next three terms in the arithmetic sequence: 25, 34, 43, 52, ...

Find a₂₆ in the arithmetic sequence: -15, -35, -55, -75, ... (Hint: Write the explicit rule first, then use it to solve)

Find the 35th term in the arithmetic sequence: -10, -14, -18, -22, ... (Hint: Write the explicit rule first, then use it to solve)

Is the sequence arithmetic: 17, 9, 1, -7, ...

Find the common difference: -34, -29, -24, -19, ...

Find the common difference: 29, 21, 13, 5, ...

Find the next three terms in the arithmetic sequence: -33, -24, -15, -6, ...
