This is an AP.
\n" ); document.write( "The n-th term of an AP with first term 'a' and common difference 'd' is
\n" ); document.write( "\"t%5Bn%5D=a%2B%28n-1%29d\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here, a = 25 and d = -15.
\n" ); document.write( "So the 100-th term is
\n" ); document.write( "\"t%5B100%5D=25-%28100-1%2915\"
\n" ); document.write( "\"t%5B100%5D=25-1500%2B15\"
\n" ); document.write( "\"t%5B100%5D=-1460\"
\n" ); document.write( "
