1). В первом следует обратить внимание на пару соседних членов и от большего отнять меньший, так мы найдем разность. Например 10-6=4. Разность прогрессии 4.
2). Чтобы найти знаменатель геометрической прогрессии так-же отмечаем пару соседних членов, больший делим на меньший. У данной прогрессии знаменатель 1/3. Умножим третий член на знаменатель, получим четвертый член. 1/3*1/3=1/6.

Аноним: В смысле?
никита20142: Ну какие-то действия
никита20142: Или это уже ответ
Аноним: Там ведь все предельно просто
Аноним: 1). 10-6=4. Ответ: 4
никита20142: Так мне не нужно нечего делать? Тупо написать 10-6=4?
никита20142: Спасибо!!!
Аноним: 2). 1:3=1/3; 1/3*1/3=1/6. Ответ: 1/6
Аноним: Все
Аноним: Не за что
