Answer:
9
Step-by-step explanation:
To find the common difference, take the second term and subtract the first term
13-4 =9
Lets check:
Take the third term and subtract the second term
22-13 =9
The common difference is 9
14 = 9 - p
Move 9 to the other side
Sign changes from +9 to -9
14-9= 9-9-p
14-9= -p
5=-p
Mutiply both sides by -1 to get + p
(5)(-1)= (-p)(-1)
p= -5
Answer: p= -5
