4,6,2,12,18,14

The number is 4 .
MULTIPLY number by 1.5 (4 × 1.5 = 6)
Substract 4 from 2nd term ( 6 - 4 = 2)
Then MULTIPLY third term by 6 ( 2 × 6 = 12)
Repeat these steps now

12 × 1.5 = 18
18 - 4 = 14
14 × 6 = 84
84 × 1.5 = 126
126 - 4 = 122
And so on

So the series is 4,6,2,12,18,14,84,126,122

4 x 3 = 12
6 x 3 = 18
2 x 7 = 14 — OR — 18 - 4 = 14 (on analogy with 6–4 = 2)

key 4 ele 1.5

1st Curr(4) x ele(1.5) = 6
2nd Curr(6) - key(4) = 2
--------------------------------------
3rd Curr(2) x Prev(6) = 12
----------------------------------------
1st Curr(12) x ele(1.5) = 18
2nd Curr(18) - key(4) = 14
-----------------------------------------
3rd Curr(14) x Prev(18) = 252
