How to find the sum of the first 10 terms of each arithmetic sequence?\r

\n" ); document.write( "\n" ); document.write( " 2. a (sub1) = 10 and a(sub10) = 55

Use the formula for the sum of an AP: \"S%5Bn%5D+=+%28n%2F2%29%28a%5B1%5D+%2B+a%5Bn%5D%29\", where:
\n" ); document.write( "\"S%5Bn%5D\" = Sum of the 1st 10 terms (\"S%5B10%5D\", in this case)
\n" ); document.write( "\"n\" = Number of terms (10, in this case)
\n" ); document.write( "\"a%5B1%5D\" = 1st term (11, in this case)
\n" ); document.write( "\"a%5Bn%5D\" = Value of last term (38, in this case) \n" ); document.write( "
\n" );
