First we need to know price per lb. we can calculate that with the info provided. So 10.5/2.5=4.2
So $4.20 per lb.
Double check that work before calculating the rest of the problem: 2.5(4.2)=10.5
So if 1 lb cost $4.20 we can multiply 5 1/4 or in decimal form 5.25(4.2)=22.05
So the total cost for 5 1/4 lbs is $22.05

The sequence an = 8, 13, 18, 23, ... is the same as the sequence a1 = 8, an = an-1 + 5.
harkovskaia [24]
Actually, this answer would be true. Why?

 The first equation is: a(sub <em>n</em>) = 8, 13, 18, 23

The second is: a(sub 1)=8 ; a(sub <em>n</em>)= a(sub <em>n</em>-1)+5
if you wish to find the second term, plug two into the equation for <em /><em>n</em> 
8+5=13
to find the third, plug the second term, 13, in for <em>n.</em> 
13+5=18.

Hope this helped! I know it's a bit on the late side, but at least you can get the general idea!
