1 + 1 + 1 + 1 + …

As the number of terms approaches infinity, the sum of the terms approaches infinity and the series diverges.

• Example: Will Series U converge?

U = 1 + 1/2 + 1/3 + … + 1/n + …

(This is called the Harmonic Series.)

Compare with the known Series K, which diverges as more terms are added.

K = 1 + 1/2 + 1/2 + 1/2 + …

To compare Series K to Series U rewrite Series K as:

K = 1 + (1/2) + (1/4 + 1/4) + (1/8 + 1/8 + 1/8 + 1/8) + …

Compare Series K to Series U term by term.
