RAKESH  (10 years ago)

there are two series
(2,4,6,8,10, ) & (1,3,6,10, )
in 1st series next term is 2 more than previous so (2,4,6,8,10,12 )
in 2nd series next term is 10+5=15
so next two term
15,12

Ans = 15
Soln -
There are 2 series
1st is addition of 2 i.e
2+2=4
4+2=6
6+2=8
8+2=10
other series is addition of sequence 2,3,4, and so on starting from 1
1+2=3
3+3=6
6+4=10
10+5=15

swathi sri  (10 years ago)

here 1st,3rd,5th,7th,9th are divisible by 2 so 11th number is 12
2nd,4th,6th,8th numbers are
1+2=3 is 4th num
3+3=6 is 6th num
6+4=10 is 8th num
next 10th place number is 10+5=15
so ans is 15,12

C.GIRIBABU  (10 years ago)

1.alternate digits are multiples of 2..from this last digit may come 12
2.and even places of the digits are increses exponentially +1,+2,+3,..so the next no will come +4=15,
the sequence is 2,1,4,3,6,6,8,10,10,15,12

Is this solution Helpfull? Yes (2) | No   

Pratanu Ranjan De  (10 years ago)

15 and 12
two series are present alternately
series1: 2,4,6,8,10,12( here 2 is added to next term in the series)
series2: 1,3,6,10,15( here incrementing order is added that is to get 2nd term we add 2 to 1st term, to get the 3rd term we add 3 to the 2nd term and so on..)

akash  (10 years ago)

(!)2 4 6 8 10
(!!) 1+2=3+3=6+4=10=10+4=14
Answer is 14. First series in even numbers and in second series numbers added to the next number in sequence like 1 2 3 4 so at the end after 10 we have to add 4 in 10 so 10+4=14

Kishore  (10 years ago)

ans: 15,12
it is combination of two series
1,3,6,10,15 (position+previous number)
2,4,6,8,10,12 (differece b/t numbers is 2)

Is this solution Helpfull? Yes | No   

AMIT JAISWAL  (10 years ago)

here in the first series 2,4,6,8,10 so next will be 12 as each term is incrementing by 2
and in second series 1,3,6,10 each term is incrementing than the next term is 2,3,4,5 so next no will be 15.

12 and 15 will be the next term

suresh  (10 years ago)

separate odd position nums and evens position nums
2 4 6 8 10 -- differece is 2 so next num is 12
1 3 6 10 15 -- diffrence is increment n+1, so next num is 15
