The average growth rate would be (3+1-2+4+5)/5 = 2.2%
The decrease from 1% to -2% would be what they call, economic recession, when the economy of a country, for example, decreases probably due to calamities.
If it would have been +2%, then the average growth rate would be:
(3+1+2+4+5)/5 = 3%
X=5
This is because you divide 20/4 since you divide 4 from each side.
