The given series is 201,202,204,207,?
The difference is 1,2,3 and so on like a series
So to add 4 => 207+4=211
The answer is 211

The given series is 201,202,204,207,---
1,2,4,7,--
1+1=2
2+2=4
4+3=7
7+4=11
the answer is 11

Hey it's very easy.

(201)+1 = (202)+2 = (204)+3 = (207)+4 = (211);

So answer is: 211.

1+1 = 2.
2+2 = 4.
4+3 = 7.
7+4 = 11.
Answer = 11.

Hey friends.

Whole no are being added consecutively to the next no.

As 201+1=201.
202+2=204.
204+3=207.
207+4=2011.

So the answer is 211.

Is that clear?

201+1 = 202.
202+2 = 204.
204+3 = 207.
207+4 = 211.

And So on..
211+5 = 216..

Fibonacci series.

Kalaivani said: (Jul 6, 2016)  
Yes, I too understand this, Thank you all.

K.Sujitha said: (Aug 24, 2016)  
201 + 1 = 202,
202 + 2 = 204,
204 + 3 = 207,
207 + 4 = 211.

Jhansi said: (Aug 24, 2016)  
As per my logic 207 + 4 = 211.

Tera Bap said: (Apr 5, 2017)  
Thanks for the all the given explanations.

Ribhu said: (Apr 6, 2017)  
Also an ans could possible by breaking it 2 series (201,204,...),(202,207,...). 1st series has difference 3 and 2nd has 5. So it's like (201,204,207...),(202,207,212...). So series like 201,202,204,207,207,212,....

N.Vishnu Vardhan Reddy said: (Apr 7, 2017)  
Yes, I understood. Thanks for all your explanation.

201+1=202
202+2=204
204+3=207
207+4=211

And so on
211+5=216.

Avitabayan said: (Nov 3, 2017)  
201+1 = 202.
