document.write( "Question 616342: I really hope that I have the right place for my questions... if I don't I am really sorry. The name of my lesson is Descriptive statistics. my question is if I have the terms 14, 6, 17 ,15,12, 22, and 19 what term do I add to this sequence to have a mean of 17? I have tried the equation $\"+.5n%2A%28n%2B1%29+\"$ and I got 36 but that doesn't give me the mean 17. What equation do I use? \n" ); document.write( "

You can put this solution on YOUR website!
Mean = (Sum of the values)/(Number of values)\r

\n" ); document.write( "\n" ); document.write( "17 = (14+6+17+15+12+22+19+x)/8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "17 = (105+x)/8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "17*8 = 105+x\r

\n" ); document.write( "\n" ); document.write( "136 = 105+x\r

\n" ); document.write( "\n" ); document.write( "136-105 = x\r

\n" ); document.write( "\n" ); document.write( "x = 31\r

\n" ); document.write( "\n" ); document.write( "So you need to add 31 to the list.\r
