### Example Question #41 : Sequences And Series

The lengths of the sides of ten squares form an arithmetic sequence. One side of the smallest square measures eight inches; one side of the second-smallest square measures one foot.

Give the area of the largest square.

**Possible Answers:**

784 square inches

484 square inches

1,936 square inches

2,304 square inches

576 square inches

**Correct answer:**

1,936 square inches

Let be the lengths of the sides of the squares in inches. and , so their common difference is

The arithmetic sequence formula is

The length of a side of the largest square - square 10 - can be found by substituting :

The largest square has sides of length 44 inches, so its area is the square of this, or square inches.
