If a working was originally $25 and it is on sale for $18 what is the percent of discount

First we must subtract 25 in 18 because we are doing percentages.

So we do

So we get 7.

Now we need to do

We would get a total of 18% of on the discount.

the first one, all those points on the line just make a strait line.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
