Step-by-step explanation:
1 * (-5) = -5 a = -5
6 + (-5) = 1 b = 1
1 * (-5 ) = -5 c = -5
-7 + -5 = -12 d = -12
52 - 37 = 15
67 - 52 = 15
82 - 67 = 15
The common difference for this arithmetic sequence is 15.

Step-by-step explanation:
The variation equation is qr = 25
<h3>How to determine the equation?</h3>
An inverse variation is represented as:
qr = k
Where k is the constant of variation
When q = 10 and r =2.5, we have:
k = 10 * 2.5
Evaluate
k = 25
Substitute k = 25 in qr = k
qr = 25
Hence, the equation is qr = 25
