Given the following sequence, find the 50th term: 1.3, 1.5, 1.7, 1.9, 2.1, is 11.1 .
Common difference = 2.1 - 1.9 = 0.2
50th term = 1.3 + (50 - 1)*0.2= 1.3 + 9.8 = 11.1 .

The value of y varies directly with x, and y = 4 when x = 1.
The equation is y = kx where k is the constant.
With given value we get k = y/x = 4/1 = 4
The equation is y = 4x
when x = 3, y = 4(3) = 12
