To add them, you first need a common denominator.
So multiply <span> 1/4 by 5/5 and 1/5 by 4/4 first. 

Now they'll be 5/20 and 4/20. 

Add them to get 9/20. </span>

Indicate a general rule for the nth term of this sequence. -6b, -3b, 0b, 3b, 6b. . .
SOVA2 [1]

The general rule for the nth term of the sequence is a(n)=-6b+(n-1)(3b)

Explanation:

The sequence is -6b, -3b, 0b, 3b, 6b, .....

To find the nth term of the sequence, we need to find the common difference and the first term of the sequence.

First term of the sequence = -6b

Common difference = -3b-(-6b)=-3b+6b=3b

Using this the nth term of the sequence can be determined.

Since, this is an arithmetic sequence, the general form of AP is given by the formula,

a(n)=a+(n-1)d

where a denotes the first term of the sequence and d denotes the common difference. Thus, a=-6b and d=3b

Substituting the values in the general formula, we get,

a(n)=-6b+(n-1)(3b)

Thus, the general rule for the nth term of the sequence is a(n)=-6b+(n-1)(3b)
