Answer:
Its 4
Step-by-step explanation:
You would have to do the formula for finding slope
y2-y1/x2-x1
John's gross monthly salary is $2000.
John receives a 15% raise in his salary.
So first we have to find 15% of $2000.
15% of 2000 = 
= 
= 
= 
John's salary including the raise = $
= $2300.
Now 30% of his monthly paycheck withheld for taxes.
30% of 2300 = 
= 
= 
= 
So the amount of tax deducted = $690.
John's net monthly income = $
= $1610.
So we have got the required answer.
Add 51 to get next number.
Proof:
5+51=56
56+51=107
107+51=158
