Question

Наступний член арифметичної прогресії 5;3;1;... дорівнює .​

Answer 1

Пусть следующий член ар. прогрессии будет х.  Разность равна 3-5=1-3=х-1

х-1=-2⇒х=-1

Answer 2

In an arithmetic progression, the difference between consecutive terms is constant. To find the next term, we need to determine the common difference (d) and then add it to the last term of the given sequence.

Given sequence: 5, 3, 1, ...

To find the common difference (d), we subtract the second term from the first term: d = 3 - 5 = -2

Now, to find the next term, we add the common difference (-2) to the last term (1): Next term = 1 + (-2) = -1

Therefore, the next term in the arithmetic progression is -1.
