The answer is b because the pattern  of these terms r that odd numbers r positive and even numbers are negative. 50 is even so it is negative, while 51 is odd so it is positive. Remember that negative numbers are below zero. If u add something to a negative number it is like subtracting positive numbers. -51+50 is -1. Because if 51 was positive it would be 51 minus 50. The answer is b. If u dont understand or if it is wrong tell me. :D 
        
             
        
        
        
Answer:
y = 36x
Step-by-step explanation:
Given that x and y vary directly then the equation relating the is
y = kx ← k is the constant of variation
To find k use the condition x =  , y = 12, then
, y = 12, then
k =  =
 =  = 12 × 3 = 36
 = 12 × 3 = 36
y = 36x ← equation of variation
