$\"1-3%2F4=1%2F4\"$ and $\"3%2F4-1%2F2=1%2F4\"$ ,
\n" ); document.write( "so the common difference of this A.P. (Arithmetic Progression, or arithmetic sequence) is
\n" ); document.write( " $\"d=1%2F4\"$ .
\n" ); document.write( "The first term is, obviously $\"a%5B1%5D=1%2F2\"$ .
\n" ); document.write( "So, as for all AP's the nth term is
\n" ); document.write( " $\"a%5Bn%5D=a%5B1%5D%2B%28n-1%29%2Ad\"$ ,
\n" ); document.write( "in this case
\n" ); document.write( " $\"a%5Bn%5D=1%2F2%2B%28n-1%29%281%2F4%29\"$ .
\n" ); document.write( "It may be easier to calculate as
\n" ); document.write( " $\"a%5Bn%5D=%28n%2B1%29%281%2F4%29\"$ , because
