3   (+5)   8   (x6)   48   (+7)   55   (x8)   440   (+9)   449

The sequence alternates between adding and multiplying. The incremental increase is 1 each time.

3   6   9   12   15   18

The pattern to the number sequence is to add 3 each time.

C   D   E   F   G   H   I   J   K   L  M

You skip one letter each time.

AB   CD   EF   GH   IJ   KL   MN   OP   QR

You just skip 1 pair of letters each time.

10 (+7)  17  (+9)  26  (+11)  37 (+13)  50

The number sequence starts at +7 then incrementally increases by 2 each time until it reaches +13 by the end of the sequence.

3    9    5   25   8   64   12   144   17

Every pair of numbers is just the square/square root of each other.

For example:

3 x 3 = 9, 5 x 5 = 25, 8 x 8 = 64, 12 x 12 = 144

Then the sequence starts at +2 then incrementally increases by 1 each time:

3  (+2)  5  (+3)  8  (+4)   12  (+5)  17

B   C   D   E   F   G   H   I   J   K   L

You skip one letter each time.

I   J   K   L   M   N   O   P   Q   R   S

You skip one letter each time.

37  (+13)  50  (+15)  65  (+17)  82   (+19)  101

The number sequence starts at +13, then incrementally increases by 2 each time until it reaches +19 by the end of the sequence.

6   (x2)  12   (x3)   36   (x2)   72   (x3)   216  (x2)   432

The sequence alternates between multiplying by 2 and multiplying by 3.
