4-26.

Consider the arithmetic sequence *a* and *b*. Homework Help ✎

Since this sequence is arithmetic, what has to be true about the differences between terms?

How many times would you add the difference to get from 2 to 35?

Since you know the first term and the common difference, you can write all four terms of the sequence.

Use the sequence to write a system of equations: and
