Which of the following is most likely the next step in the series?
A.
B.
C.
D.

A

Step-by-step explanation:

Note that the dots in both the upper and lower row increase by 1

The 3rd diagram has 4 dots in the upper and 3 in the lower , then

the next diagram should have 5 dots in the upper and 4 in the lower

This is the case in diagram A

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

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
