Question

Write a possible explicit rule for the nth term of the sequence:
1, 1/2, 1/3, 1/4, 1/5, ...
A.an = 1/n-1
B.an = 1/an-1
C.an = 1/n2
D.an = 1/n

Answer 1

The correct option is D): "an=1/n" because:
since first term: n is 1,
if you plug in 1 in the 1/n,
you get one. second term: n=2,
so, 1/n = 1/2.
