Question

Очень срочно !!!!!! se dă un șir numeric crescător de două cifre cărei divizibil prin 13. este oare acest șir progresie? care progresie?дана восходящая числовая строка из двух цифр, которая делится на 13. Является ли эта строка прогрессией? какая прогрессия?​

Answer 1

Рассмотрим число 13 - это простое число.

На это число могут делиться нацело только числа образованные

по такому правилу

A=13*n. где n целое число

попробуем составить такой ряд

$\displaystyle A_1=13; A_2=26; A_3=39\\\\A_2-A_1=26-13=A_3-A_2$

Значит мы получили Арифметическую прогрессию

Answer 2

Based on the search results, I couldn't find a direct answer to your question. However, I can provide you with some information that might help you understand the concept of progressions and determine if the given sequence is a progression.

Progressions:

A progression is a sequence of numbers in which the difference between consecutive terms remains constant. There are different types of progressions, such as arithmetic progressions and geometric progressions.

- Arithmetic Progression: In an arithmetic progression, the difference between consecutive terms is constant. For example, the sequence 2, 5, 8, 11, 14 is an arithmetic progression with a common difference of 3.

- Geometric Progression: In a geometric progression, the ratio between consecutive terms is constant. For example, the sequence 2, 6, 18, 54, 162 is a geometric progression with a common ratio of 3.

Analyzing the Given Sequence:

To determine if the given sequence is a progression, we need to check if the difference between consecutive terms remains constant.

Unfortunately, I don't have the specific sequence you mentioned in your question. However, if you provide the sequence, I can help you analyze it and determine if it is a progression.

Please provide the sequence so that I can assist you further.
