For the series 1/2 , 1/4 , 1/6 , 1/8 , 1/10, 1/12, 1/14, 1/16 what isthe nth term?

The given terms of the series
are:

1/2, 1/4, 1/6, 1/8, 1/10 1/12, 1/14, 1/16
...

Thus

Term number 1 = 1/2 =
1/(1*2)

Term number 2 = 1/4 
1/(2*2)

Term number 3 = 1/6 =
1/(3*2)

Term number 4 = 1/8 =
1/(4*2)

Term number 5 = 1/10 =
1/(5*2)

Term number 6 = 1/12 =
1/(6*2)

Term number 7 = 1/14 =
1/(7*2)

Term number 8 = 1/16 =
1/(8*2)

Term number n =           
1/(n*2)

Answer:

nth term =
1/(n*2)
