J + -2 = -22
Adding a negative number changes the equation to subtract ruin:
J - 2 = -22
Now add 2 to both sides to get the answer:
J = -20

because a linear changes at a constant rate and an exponential changes by a common ratio
Answer:

The number is 8 because 
And if you add 4, you get 20
Hence, the number is 8
