Homework Help: Math

Posted by Tori on Thursday, January 11, 2007 at 11:43pm.

I am stuck on a couple of math problems. I need help on the following numerical patterns.

5,7,11,17,25,?,47,61

80,40,20,?,5,5/2

It looks like you add two to each increment. For example,
5 + 2 = 7.
7+4=11
11+6=17
17+8=25
25+10=35 etc.

For #2, I think each is halved.
80/2=40
40/2=20
etc.
