Determine the sum of the 15 terms of the arithmetic series where the 5th term is 4 and consecutive terms increase by 3.
\n" ); document.write( "A) 195
\n" ); document.write( "B) 285
\n" ); document.write( "C) 182
\n" ); document.write( "D) 169
\n" ); document.write( "
With the 5th term being 4, we get:   
\n" ); document.write( " Formula for the sum of an AP: \"matrix%281%2C3%2C+S%5Bn%5D%2C+%22=%22%2C+%28n%2F2%29%282a%5B1%5D+%2B+%28n+-+1%29d%29%29\"
\n" ); document.write( "
\n" ); document.write( " Sum of the 1st 15 terms of AP, or \n" ); document.write( "
\n" );
