Which number will replace the question mark (?) in the following series?

4, 16, 36, 64, 100, 144, 196, ?

284

225

256

246

The pattern followed in the series is

4 + 12 = 16
16 + 20 = 36
36 + 28 = 64
64 + 36 = 100
100 + 44 = 144
144 +52 =196

So following the same pattern we will get the answer
196 + 60 =256

Hence option 3 is the correct answer.
