12 x 2 = 42 14 x 3 = 42 7 x 6 = 42 6 x 7 = 42 2 x 12 = 42 3 x 14 = 42
12+5 = 6 22+5 = 9 32+5 = 14 42+5 = 21 52+5 = 30 62+5 = 41 Square the sequence number then add 5.
They are 14, 42, 126, 378 and 1134.
12 + 14 + 16 = 42
This is a three step sequence of operations. (1) -4 : (2) ÷3 : (3) x2 46 - 4 = 42 : 42 ÷ 3 = 14 : 14 x 2 = 28 28 - 4 = 24 : 24 ÷ 3 = 8 : 8 x 2 = 16 The next number is therefore 16 - 4 = 12.
From the given sequence, the pattern appears to be 47-42=4, 42/3=14, 14*2=28, 28-4=24, 24/3=8, 8*2=16 and therefore the next number will be 16-4=12.
A single number, such as 4642142824816 does not constitute a sequence.
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
12 x 2 = 42 14 x 3 = 42 7 x 6 = 42 6 x 7 = 42 2 x 12 = 42 3 x 14 = 42
12+5 = 6 22+5 = 9 32+5 = 14 42+5 = 21 52+5 = 30 62+5 = 41 Square the sequence number then add 5.
3, 12/3 = 4, and 42/3 = 14
70. You just add 14 each time.

They are 14, 42, 126, 378 and 1134.
12: 12, 24, 36, 48, 60, 72 14: 14, 28, 42, 56, 70, 84
