4/3+16/15+36/35+64/63+100/99+144/143+196/195+256/255

=[1+1/3]+[1+1/15]+[1+1/35]...+[1+1/255]

=1*8+1/1*3+1/3*5+1/5*7+....+1/15*17

=8+1/2[1-1/3]+1/2[1/3-1/5]+1/2[1/5-1/7]+...+1/2[1/15-1/17]

=8+1/2[1-1/3+1/3-1/5+...+1/15-1/17]

=8+1/2[1-1/17]

=8+1/2*16/17

=8又8/17

=8+（1/3+1/15+1/35+....+1/225)
=8+1/2(1-1/3+1/3-1/5+......+1/15-1/17)
=8+1/2(1-1/17)
=144/17
