Joey needs to take a new prescription. The first day he needs to take one pill. Each day he must take two more pills than the previous day. How many pills will he take in a week?
For the second day he takes 1 + 2 = <<1+2=3>>3 pills.
For the third day he takes 3 + 2 = <<3+2=5>>5 pills.
For the fourth day he takes 5 + 2 = <<5+2=7>>7 pills.
For the fifth day he takes 7 + 2 = <<7+2=9>>9 pills.
For the sixth day he takes 9 + 2 = <<9+2=11>>11 pills.
For the seventh day he takes 11 + 2 = <<11+2=13>>13 pills.
For the entire week he takes a total of 1 + 3 + 5 + 7 + 9 + 11 + 13 = <<1+3+5+7+9+11+13=49>>49 pills.
