HERE WE CAN JUST SPLIT THE SERIES AS;
1 2 3 6
9 18 ? 54
NOW YOU CAN EASILY FIND THAT 1*9= 9.
2*9 = 18,
AND 6*9= 54 S0,
3 *9 = 27.
1 2 3 6
9 18 ? 54
NOW YOU CAN EASILY FIND THAT 1*9= 9.
2*9 = 18,
AND 6*9= 54 S0,
3 *9 = 27.

1, 2, 3, 6, 9, 18, ?, 54.
1 + 2 = 3,
1 + 2 + 3=6,
3 + 6 = 9,
3 + 6 + 9 = 18,
9 + 18 = 27.
9 + 18 + 27 = 54.
1 + 2 = 3,
1 + 2 + 3=6,
3 + 6 = 9,
3 + 6 + 9 = 18,
9 + 18 = 27.
9 + 18 + 27 = 54.

By paring alternate number we can find 2/1 = 2
6/3 = 2
18/9 = 2.
54 should be twice of a number that is =27.
So, when 54/27=2.
6/3 = 2
18/9 = 2.
54 should be twice of a number that is =27.
So, when 54/27=2.

2-1 = 1,
3-2 = 1,
6-3 = 3,
9-6 = 3,
18-9 = 9,
x-18 = 9,
x = 18 + 9 = 27.
3-2 = 1,
6-3 = 3,
9-6 = 3,
18-9 = 9,
x-18 = 9,
x = 18 + 9 = 27.

1, 2, 3, 6, 9, 18,.....,54.
Take alternate positions 2 6 18 54.
2*3=6.
6*3=18.
18*3=54.
Each multiplying with 3.
Similarly take the alternate numbers 1 3 9.
1*3=3.
3*3=9.
9*3=27.
This is also a method which holds good for many problems.

2 * 9 = 18.
And 6 * 9 = 54 so,
3 * 9 = 27.
And 6 * 9 = 54 so,
3 * 9 = 27.
