You can put this solution on YOUR website!
first term t1 = 5(1)-2 = 3\r
\n" ); document.write( "\n" ); document.write( "second term t2= 5(2) - 2 = 8\r
\n" ); document.write( "\n" ); document.write( "so, sequence is an Arithmetic Progression 3,8,13,18..........\r
\n" ); document.write( "\n" ); document.write( "here common difference = 5\r
\n" ); document.write( "\n" ); document.write( "let there are total x terms then
\n" ); document.write( "
\n" ); document.write( "tx= 5x - 2\r
\n" ); document.write( "\n" ); document.write( "=> 148 = 5x -2 \r
\n" ); document.write( "\n" ); document.write( "=> x = 150/5 = 30\r
\n" ); document.write( "\n" ); document.write( "there are 30 terms.\r
\n" ); document.write( "
