104 is the first natural number divisible by 4 (between 100 and 200)
196 is the last number divisible by 4 (between 100 and 200)
104, 108.....196
Its an A.P(Arithmetic Progression) with common difference '4'.
Number of terms = 24
Sum = n/2 * (A1 + An)
= 24/2 * (104+196)
=12*300 = 3600
Hope it helps
