Consider the arithmetic sequence 13, 24, 35,
b. find the 40th term.

40th term of arithmetic sequence = 442

Step-by-step explanation:

Here arithmetic sequence is given as 13, 24, 35, ....

First term, f = 13

Common difference , d = 24 - 13 = 11

We know that n th term of AP is

We need to find 40 th term, that is n = 40

Substituting

40th term of arithmetic sequence = 442

cosine

step-by-step explanation:

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
