The sum of the first four terms of a linear sequence A.p is 26
\n" ); document.write( "
Let a = first term and d = common difference\r\n" );
document.write( "\r\n" );
document.write( "\"a%2B%28a%2Bd%29%2B%28a%2B2d%29%2B%28a%2B3d%29=26\"\r\n" );
document.write( "\"4a%2B6d=26\"\r\n" );
document.write( "\"2a%2B3d=13\"
and that of the next four term is 74.\r
\n" ); document.write( "\n" ); document.write( "\"%28a%2B4d%29%2B%28a%2B5d%29%2B%28a%2B6d%29%2B%28a%2B7d%29=74%29\"
\n" ); document.write( "\"4a%2B22d=74\"
\n" ); document.write( "\"2a%2B11d=37\"\r
\n" ); document.write( "\n" ); document.write( "find the value of the first term ,the common difference
Solve the system:\r\n" );
document.write( "\r\n" );
document.write( "\"system%282a%2B3d=13%2C+2a%2B11d=37%29\"\r\n" );
