Find an equation for the nth term of the arithmetic sequence.

-13, -8, -3, 2,

an = -13 x 5(n - 1)
an = -13 + 5(n - 1)
an = -13 + 5(n + 2)
an = -13 + 5(n + 1)

Option B.

Step-by-step explanation:

The given arithmetic sequence is

We need to find the nth term of the given arithmetic sequence.

Here,

First term :

Common difference :

The nth term of an arithmetic sequence is  

where, a is first term and d is common difference.

Substitute a=-13 and d=5 in the above formula.

Therefore, the correct option is B.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
