Does anyone know what this following sequence is called?

3,6,12,24,48......

I saw somewhere that it is similar to Pisot sequence. Can anyone confirm?

Mucho gracias, me hombres!
 
Bodes law just uses the numbers.... it doesnt look like its the name of the sequence.

Every number is multiplied by 2. 3, 6, 12, 24, 48 and then 96, 192 etc.

I did not meant this as a brain teaser. My son was asked to research and come up with the name or term to describe the sequence. I could not find anything online and thought maybe one of you clever cloggs would know.
 
Ive had another look and cant find a name for it. I found the reference to a Pisot sequence but I wouldnt use that.
My final answer is geometric...... a, ar, ar^2, ar^3, ar^4 etc where a = first number (in this case 3) and r = 2.

The formula is (nth term) An=ar^n-1

ie the 12 term (when n=12) is 6144 ..... 3x2^11
