The next number in the sequence is 15 - the sequence goes x2, +2, -1
15
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.
15 + 1 = 16 sum 15 - 1 = 14 difference
1 .... - 1, 1+4(square of 2) - 5, 1+4+9(square of 3) - 14, 1+4+9+16(square of 4) - 30, 1+4+9+16+25(sqaure of 5)- 55,
This is a 4 step sequence , starting with the number 1. 1) Double the number 2) Add 2 3) Subtract 1 4) Return to step 1) and repeat. 1 x 2 = 2 ; 2 + 2 = 4 ; 4 - 1 = 3 ; ..........7 x 2 = 14 ; 14 + 2 = 16. Then the next number is generated by Step 3).. 16 - 1 = 15
The simplest sequence appears to be 15 1*2=2 2+2=4 4-1=3 3*2=6 6+2=8 8-1=7 7*2=14 14+2=16 16-1=15 Multiply by 2 Add 2 Subtract 1 Repeat
x 2 + 2 - 1 is the repeating sequence 1 x 2 = 2 2 + 2 = 4 4 - 1 = 3 3 x 2 = 6 6 + 2 = 8 8 - 1 = 7 7 x 2 = 14 14 + 2 = 16 16 - 1 = 15 the next number is 15

The next set in the pattern would be 5 to 22. The pattern is to increase the first digit by 1, second digit by 2.
The common factors of 14 and 16 are 1 and 2.
