You can  put this solution on YOUR website! 1) each entry is 2 times the previous entry. Geometric 
2) each entry is 2 greater than the previous entry. Artimetic 
3) each entry is (n+1) times the previous entry. 2 = 1*2, 6 = 2*3, 24 = 6*4. Geometric  
4) each entry is 7 more than the previous entry. Arithmetic

You can  put this solution on YOUR website! I'll do the first two to get you started
 
 
1. 3,6,12,24,...
 
 
Notice how each term is multiplied by 2 to get from term to term. In other words, 3*2=6, 6*2=12, 12*2=24, etc. So this means that the sequence is the geometric pattern   where "n" starts at zero. If you want "n" to start at 1, then the sequence is  
 
 
 
 
 
 
2. 1,3,5,7,...
 
 
 
To get from term to term, simply add 2 to each term. In other words, 1+2=3, 3+2=5, 5+2=7, etc. So this means that the sequence is the arithmetic pattern   where "n" starts at zero. If you want "n" to start at 1, then the sequence is
