- 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 - 6 years agoHelpfull: Yes(8) No(4)

- 4 x 3 = 12
6 x 3 = 18
2 x 7 = 14 — OR — 18 - 4 = 14 (on analogy with 6–4 = 2) - 6 years agoHelpfull: Yes(1) No(2)

- Actually really simple, dont listen to the nonsense here, the answer is 6 because it is the only even number you have in your oprtions, 84, 21 and whatever else is suggested arent present in your choices
