Why don't you add up 1 with the other consecutive terms.

1+3+4=8
3+4+8=15
4+8+15=27
8+15+27=50
hence,the series is 1,3,4,8,15,27,50..
we need to add the three consecutive terms in order to find the next term.

1+3 = 4.

4+(1+3) = 8.

8+(3+4) = 15.

15+(4+8) = 27.

27+(8+15) = 50.

Must it be in that series to get the answer? there should be another way out. Adding the difference between each and multiplying by the first two difference.

25 x 2 = 50.

Can anyone tell me?

Why your logic does not fit on 3 also. You are starting with taking first two number 1 and 3, why?

If it is sequence it should follow for (2nd digit is) 3 also.

Please explain me.
