10.2 inches

Step-by-step explanation:

The initial diameter of the base ball is 20 inches

Reducing this diameter by 20% means; (100-20)/100 * 20

80/100 *20 =16 inches

Reducing this diameter by 20% for the second time gives

80/100* 16 = 12.8 inches

Reducing this for the third time gives;

80/100 * 12.8 =10.24 inches

In mathematics, the Nth harmonic number is defined to be 1 + 1/2 + 1/3 + 1/4 + ... + 1/N. So, the first harmonic number is 1, th
Andreyy89

Answer:

cl   +   1/(N+1)

Step-by-step explanation:

If we assume that the Nth harmonic number is cl. Then we are assuming that 1+1/2+1/3+1/4+...+1/N=cl

And we know that the (N+1)th harmonic number can be found by doing

1+1/2+1/3+1/4+...+1/N+1/(N+1)

=cl    +   1/(N+1)

The (N+1)th harmonic number is cl   +   1/(N+1) given that the Nth term is cl

Other way to see the answers:

Maybe you want to write it as a single fraction so you have

[cl(N+1)+1]/(N+1)=[cl*N+cl+1]/(N+1)
