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

The general rule for the nth term of the sequence is

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 =

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,

where a denotes the first term of the sequence and d denotes the common difference. Thus, and

Substituting the values in the general formula, we get,

Thus, the general rule for the nth term of the sequence is

the discriminant is 64 + 4*1*12 = 112

this is prime.
