- 1,3,3,2,8,10,3,4,12,4,8,..?
1*3=3
2+8=10
3*4=12
4+8=12
so ans is 12 - 11 years agoHelpfull: Yes(58) No(1)
- multiply the first two numbers i.e 1 and 3.It gives the third number 3..
Then multiply the next two numbers and substract 6 from it.It gives the next number...
Then again alternative multiplication of next numbers gives the next number in the in the series.. Hence the next numbers are 4 and 8 ..multiplication of these two numbers are 32 ..according to the series substract 6 from it.. Hence the answer is 26.. - 12 years agoHelpfull: Yes(5) No(11)
- 1*3=3 ->1,3,3
2+8=10 -> 2,8,10
3*4=12->3,4,12
4+8 =12

- 3 series
1,2,3,4
3,8,4,8
3,10,12,?
so next term may be 14 - 12 years agoHelpfull: Yes(3) No(18)
- The answer is 17.
1,3,3 ------> 1, (2), 3, (0) 3 => [ 3-1=2; 3-3=0] ------- > (2+0=2 (used in next row right)
2,7,10------> 2, (6), 8, (2) 10 => [ 8-2=6; 10-8=2] ------ > (6+2=8 used in next row right)
3,4,12-------> 3, (1), 4, (8), 12 => [4-3=1; 12-4=8] -------> (1+8=9 should be used in next row right)
4,8,x -------> so, the ans will be => 4, (4), 8 (9), 17 ->> ANSWER !!!! - 9 years agoHelpfull: Yes(2) No(6)
- 1*3=3

- in this question we can solve by this way.
STEP FIRST-(1,3,3) TAKE PAIR OF THREE NUMBER THEN FIRST TWO NUMBER MULTIPLY TO EACH OTHER.
STEP TWO-(2,8,10) ADD TWO INTIAL NUMBER THEN YOU WILL GET LAST NUMBER..DO AS FOLOOW - 8 years agoHelpfull: Yes(1) No(2)
