Answer:
the common difference of the sequence is 
Step-by-step explanation:
A sequence of numbers is said to be in arithmetic progression of each term of the sequence has same common difference.
Now, here first term a1 = 1/4
Second term a2 = 5/16
Third term a3 = 3/8
Now, Common difference (d) = a2 - a1 = a3 - a2
Now, a2 - a1 = 
Now, a3 - a2 = 
Hence, the common difference of the sequence is 
Answer:
<h2>k(-1) = 7</h2>
Step-by-step explanation:
Look at the picture.
Formula:

x + 2x + 2 = 17
3x + 2 = 17
3x = 15
x = 5
So, the answer is 5 and 6
