<span>For this case we have the following data:
 (1, 24), (2, 24.38), (3, 24.76), (4, 25.14)  
 We observe that, we have an arithmetic sequence.
 That is, we have:
 </span>an + 1 = an + d &#10;
 <span>Where,
 an + 1: next term
 an: previous term
 d: common difference.
 So we have to clear d:
</span> d = an + 1 - an &#10;
<span> Substituting any values of the table (coordinate y) we have:
</span> d = 24.38 - 24 &#10;&#10;d = 0.38<span>
 Answer:
 a. The common difference is 0.38</span>

a rectangular pyramid has a volume of 190 cubic centimeters. Find two possible sets of measurements for the base area and height
DerKrebs [107]
<h3>One possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively</h3><h3>Other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively</h3>

<em><u>Solution:</u></em>

<em><u>The volume of rectangular pyramid is given as:</u></em>

Volume = \frac{1}{3} \times base\ area \times height

Given that,

<em><u>Rectangular pyramid has a volume of 190 cubic centimeters</u></em>

<em><u></u></em>190= \frac{1}{3} \times base\ area \times height<em><u></u></em>

<em><u>Substitute, base area = 570 and height = 1</u></em>

Then we get,

190 = \frac{1}{3} \times 570 \times 1\\\\190 = 190

Thus one possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively

<em><u>Substitute, base area = 285 and height = 2</u></em>

190 = \frac{1}{3} \times 285 \times 2\\\\190 = \frac{1}{3} \times 570\\\\190 = 190

Thus other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively
