Answer:
r+p=-8
Step-by-step explanation:
5-p=r-3
5+3-p-r=0
8-p-r=0
r+p=-8
<em><u>The common difference d is </u></em>
<em><u>The first term is</u></em>
<em>so , the first term is -13 </em>
8 * 63 = 8 * ? + 8 * 3 = ?
Okay, so we have 8 * 63, and it is broken down to 8 * ? + 8 * 3.
63 - 3 = 60, so our number should be 60.
8 * 63 = 8 * 60 + 8 * 3 = ?
To find the last number, we can just multiply 8 * 63, which is 504.
8 * 63 = 8 * 60 + 8 * 3 = 504
