Find the arithmetic mean a n of the given terms. a n₋₁ = 0.3, a n₊₁ = 1.9
1 answer:
The arithmetic mean a n of the given terms a n₋₁ = 0.3, a n₊₁ = 1.9 is
a n = 1.6.
<h3>What is direct variation?</h3>
a n₋₁ = 0.3, a n₊₁ = 1.9
a n = a - a
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.
