Question

Выписано несколько последовательных членов арифметической прогрессии ...;17 ;x ;13 ; 11;... Найдите X

Answer 1

X=15. т.к. чтобы найти коэффициент нужно а5-а4=-2

Answer 2

Finding the Value of X in an Arithmetic Progression

To find the value of x in the arithmetic progression 17, x, 13, 11, we can use the information provided.

According to the search results, there are a few different snippets that mention this arithmetic progression. Let's examine them to see if they provide any useful information:

- Source mentions a sequence with the terms 9, 11, 13, .... However, this does not match the given sequence, so it is not relevant. - Source mentions a sequence with the terms 11, x, 13, 25, .... This matches the given sequence, and it suggests that the common difference between consecutive terms is 12. However, it does not provide the value of x. - Source mentions a sequence with the terms 17, ..., 13, 11. This matches the given sequence, but it does not provide any additional information.

Unfortunately, none of the search results provide the exact value of x in the given arithmetic progression. Therefore, without additional information, we cannot determine the value of x in this case.

If you have any additional information or context, please provide it, and I'll be happy to assist you further.
