Solution for the pattern: 3 3 4 8 10 36 ?
Sequence Pattern: 3 3 4 8 10 36 ?Solution: Odd Sequence Starting from First : 3 4 10 ? Even Sequence Starting from Second : 3 8 36 Calculating Odd Sequence: (3 * 1) + 1 3 (4 * 2) + 2 10 (10*3) + 3 33 Ans Note: Multiplication is happening with consecutive numbers and so is the addition. Calculating Even Sequence: (3*2) + 2 8 (8*4) + 4 10 (10*6) + 6 66 Note: Multiplication is happening with even numbers and so is the addition.Hence the final sequence would be 3 3 4 8 10 36 33 (Ans) 66

RE: Hi friendz, This sequence is from ibm pape...
3 3 4 8 10 36 ...
there are 2 sequences both start from 3..
the sequence 3 4 10....has the first number 3
next 3*1+1 4
4*2 +2 10
10*3+ 3 33
now...
he sequence at even places
3*2 +2 8
8*4 +4 10
10*6 +6 66
so the numbers are 3 3 4 8 10 36 33 66

RE: Hi friendz, This sequence is from ibm pape...
the digit count of the sequence isof the form..... (ie)1+5 6 3+0 3 2+8 1 etc.
6 3 1 7 2 7 1 .....so the remaining two nos. should have the count 3 and 6 respectively.....
moreover the flow of the sequence is "the second no. is greater than first and all other are less upto the no. with count 2(i.e) middle no.

and the no. next to middle no. (i.e)34 is greater than 20...
so all others should be less than 34....

on keeping all these in mind... v ll have 21 : 2+1 3
15 : 1+5 6

so the sequence is 15 30 28 25 20 34 28 21 15
