    Арифметикалық прогрессияның қосындысын қалай есептеуге болады?

    Нейро

    Ответ создан на основе результатов поиска

    Арифметикалық прогрессияның алғашқы n мүшесінің қосындысын есептеу үшін мына формуланы қолдануға болады:
    $S_n = \frac{a_1 + a_n}{2} * n$ 25.
    Арифметикалық прогрессинда әрбір келесі саны (2-саннан бастап) алдыңғысына бір тұрақты d санын қосқанда шығатын сандар тізбегі болып табылады 35.
