Indicate the general rule for this sequence. Find a1 and the common difference. a4 = 18 a7 = 9

Step-by-step explanation:

Arithmetic sequences concepts:

The general rule of an arithmetic sequence is the following:

In which d is the common diference between each term.

We can expand the general equation to find the nth term from the first, by the following equation:

And also:

In this question:

Finding the common ratio:

Finding the first term:
