The first term of an AP is 24 and 4 points
the last term is -16. If the sum of
the sequence is 24, find the
number of terms
7
6
5

2/3

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

explanation:

remove parenthesis:

=

apply rule

=

multiply fractions:

=

=

divide:

=
