You could substract or divide It to get the sum.
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)
Ah, college mathematics.
We must remember there are four quarts per gallon. Let's convert everything to gallons:
3 \frac 1 4 - 1 \frac 3 4 = \frac{13}{4} - \frac{7}{4} = \frac{6}{4} = 1 \frac 2 4
We don't reduce because it's easy to see that's 1 gallon, 2 quarts, third choice.
