Объём памяти любого запамянающего устройства компьютера можно выразить как а битах, так и мегабайтах. Однако маркитологи пришли к выводу, что выражение объема оперативной памяти в <u>гигабайтах</u> выгоднее с финансовой точки зрения.

Это простая замена, PHP, я когда-то наспех делал, пригодится может:)</span>
Увеличение в 4 раза, арифметическая прогрессия a1=5 d=4
сумма арифметической прогрессии аn=a1+d(n-1)*2/n=324
в результате имеем квадратное уравнение 2*n*n+3*n-324=0
решаем квадратное уравнение - вот только отсюда начинается программирование.
<span>начало -> [ d = 3*3-4*2*(-324) ]-> < d > 0? > -> [ n = (-3 + sqrt(d))/(2*2) ] -> / вывод n / ->
вот и всё, обращайся</span>
