Question

Find the arithmetic mean a n of the given terms. a n₋₁ = 0.3, a n₊₁ = 1.9

Answer 1

The arithmetic mean a n of the given terms a n₋₁ = 0.3, a n₊₁ = 1.9 is

a n = 1.6.

What is direct variation?

a n₋₁ = 0.3, a n₊₁ = 1.9

a n = a $n_{+1}$ - a$n_{-1}$

a n = 1.9 - 0.3

a n = 1.6

Direct variation is the change in one quantity as a result of the change in another. This suggests that if one quantity rises or falls, the other must rise or fall correspondingly as well.

The formula y = kx is used to answer direct variation questions. If finding the proportionality constant is necessary, the answer is obtained by dividing y by x.
