Пояснення:

В арифметичній прогресії кожний її член, починаючи з другого, дорівнює середньому арифметичному сусідніх членів. Зважаючи на це, складемо й розв'яжемо рівняння:

$2x - 1 = \frac{x - 1 + ( {x}^{2} - 5)}{2} \\ 2(2x - 1) = x - 1 + {x}^{2} - 5 \\ 4x - 2 = {x}^{2} + x - 6 \\ {x}^{2} - 3x - 4 = 0 \\$
