Solve for k, the constant of variation, in a direction variation problem where y = 240 and x = 30.

Minchanka [31]

$\bf \qquad \qquad \textit{direct proportional variation}
\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we also know that }
\begin{cases}
y=240\\
x=30
\end{cases}\implies 240=k30
\\\\\\
\cfrac{240}{30}=k\implies 8=k$

This is an arithmatic progression.

The formula for the sum of arithmatic progression is

$s = \frac{n}{2} (2a + (n - 1)d)$

where d is the common difference between successive terms and a is the first term. By applying this formula,

$120 = \frac{n}{2} (2(1) + (n - 1)(1)) \\ 120 = \frac{n}{2} (1 + n) \\ n(1 + n) = 240 \\ n {}^{2} + n - 240 = 0 \\ (n - 15)(n + 16) = 0 \\ n = 15 \: or \: n = - 16(reject)$
