SUNIL MAURYA  (11 years ago)

two diff series
3,5,10,18....
and
4,6,11.....
in both serise a common diff that increment with 3
as like 2,5,8,11,14
then next digit is 30+14=44 ans

there are no two series guys..its simple
take pair of 2 numbers every time & u will see difference of 1 in each pair like:
(4,3),(6,5),(11,10),(19,18),(30,29)
& then for the next number if u observe that between last & first digit of each pair there is a difference +3, +6, +9 , +12
so add 29+15 = 44 ........& this is ur ans.
& after this

rahul garg  (11 years ago)

Ans:-44
Explanation:-6-4=2,5-3=2
11-6=5,10-5=5
19-11=8,18-10=8

so series will become 2,5,8,11
so next will be 30+14=44

Is this solution Helpfull? Yes (2) | No (2)  

jashni  (11 years ago)

The next no would be 44.
Here second no is one less than first,4th is one less than 3rd etc.So 4,6,11,19,30 form a series .Difference between adjacent nos form another series 2,5,8,11 with common difference 3.So 11+3=14 hence 30+14=44

Is this solution Helpfull? Yes (1) | No (2)  

nishant saha  (7 years ago)

We consider 2 series:
4,6,11,19,30 and
3,5,10,18,29.
Now if we see the diff. between successive digits,the pattern is 2,5,8,11 and the next diff.should be 14 as a gap of 3 is the in every difference..so the next number will be
30+14=44

Khademul Islam  (7 years ago)

4-3=1
6-5=1
11-10=1
19-18=1
30-29=1
after difference between
6-3=3
11-5=6
19-10=9
30-18=12
x-29=15
therefore x=44

Is this solution Helpfull? Yes (1) | No   

nishant  (11 years ago)

series will b like this- 4,3,6,5,11,10,19,18,30,29,56,55


(4+3)-1=6
6-1=5

(11+10)-2=19
19-1=18

(30+29)-3=56
56-1=55

ANS-44
4-3=1,6-5=1,11-10=1,..
4+2=6
5+6=11,
10+9=19,
18+12=30
29+15=44

Rahul makhija  (7 years ago)

6-4=2
5-3=2
11-6=5(2+3)
10-5=5(2+3)
19-11=8(5+3)
18-10=8(5+3)
30-19=11(8+3)
29-18=11(8+3)
so next will be 11+3=14
30+14=44
29+14=43

Is this solution Helpfull? Yes | No   

Tejaswini Seethiraju  (7 years ago)

got the above series by subtracting 1 and adding multiples of 3 alternatively
4-1=3
3+(3*1)=6
6-1=5
5+(3*2)=11
11-1=10
10+(3*3)=19
19-1=18
18+(3*4)=30
30-1=29
29+(3*5)=44 ::ans=44

Is this solution Helpfull? Yes | No   

vishwa  (6 years ago)

answer:44
proof:
There are two 2 series:(4,6,11,19,30) and (3,5,10,18,29)

6-4=2;
11-6=5;
19-11=8;
30-19=11;

so new series 2,5,8,11,?
difference between each term is 3.
so next number in this series is 14.

add 14 to 30
i.e 14+30=44.
