In a sequence of numbers, a, = 16, a. = 21, a. = 31 and a, = 36, based on this information, Which of the following equation that can be used to find the nth term in the sequence, an? an = 3n + 2
an = 5n + 1
an = 2n + 2
an = 5n + 3

Step-by-step explanation:

We are checking the sequences by calculating given terms from equations:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

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
