Answer:
a21 = -61
Step-by-step explanation:
(subtract to eliminate a₁)
9 = -3d
d = -3
-19 = a₁ + (6)(-3)
-1 = a
a21 = -1 + (21 - 1)(-3)
= -61

Considering an inverse proportional relationship, you find k taking a point (x,y), and multiplying the values of x and y.
<h3>What is a proportional relationship?</h3>A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
For an inverse relationship, the function is:
.
Then:
k = xy.
Which means that to find k, you take a point (x,y), and multiply the values of x and y.
