In an AP (arithmetic progression, or arithmetic sequence),
\n" ); document.write( "\"a%5B1%5D\"= the first term,
\n" ); document.write( "\"d\"= the common difference (the difference between consecutive terms), and
\n" ); document.write( "\"a%5Bn%5D=a%5B1%5D%2B%28n-1%29%2Ad\"= the nth term ,
\n" ); document.write( "but we do not need to know any of that to answer the question.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To find the 15th term, we substitute \"n=15\" in \"4n-5\" ,
\n" ); document.write( "to find that the value of the 15th term is
\n" ); document.write( "\"4%2A15-5=60%2A5=highlight%2855%29\" .
\n" ); document.write( "
\n" );
