Consider the arithmetic series 
Let t=1 in the given series, we get
first term =
= 3-4 = -1.
Let t=2 in the given series, we get
second term =
= 
Let t=3 in the given series, we get
third term = 
Now, let t=18 in the given series, we get
last term = l = 
We get the series as
-1, 2, 5,..... 50
Sum = 
= 
= 
= 441
Therefore, the sum of the given arithmetic series is 441.
