🔣یکی از شگفتی‌های ریاضی این است که مجموع اعداد فرد متوالی همیشه به یک مربع کامل ختم می‌شود! این یعنی وقتی اعداد فرد را یکی یکی جمع می‌کنید، نتیجه همیشه یک مربع خواهد بود.
🟣به عنوان مثال: 1=1² 1+3=4=2² 1+3+5=9=3² 1+3+5+7=16=4² ... فرمول کلی این رابطه 1+3+...+(2n-1)=n²
❗️این الگو یک راز جذاب از دنیای ریاضی است که نشان میدهد چگونه یک جمع ساده می‌تواند به نتایج شگفت انگیز منتهی شود.

While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care. Groups are also not fully encrypted, end-to-end. This includes private groups.
