139, 149, 159, 169, 179, 189, 199, 209, 219, 229, 239, 249, 259.


The common difference is 13.


Let n = 52


Let d = common difference


a_52 = 139 + (52 - 1)(13)


a_52 = 139 + (51)(13)


a_52 = 139 + 663


a_52 = 802

36% of what number is 64.8?
Ivenika [448]

Set up the equation 64.8 = .36x

Divide by .36 on both sides.

You get 180 = x.

36% of 180 is 64.8

Multiply .36 by 180 to double check.

Hope this helps
