Question

Учитель подготовил для контрольной работы 42 карточки пяти цветов: белого, жёлтого, зелёного, красного, синего. Сложив все карточки в этой последовательности (б, ж, з, к, с, б, ж, ...), он пронумеровал их все подряд, начиная с номера 1. Какого цвета карточка с номером 24? с номером 38? с номером 10? последняя карточка? Решение по действиям. Пожалуйста

Answer 1

Прости я не знаю как можно решить по действиям. Я решала методом подбора 
Получилось 
Карточка под №24 зелёного цвета 
Карточка под №38 жёлтого цвета 
Карточка под №10 зелёного цвета 

Answer 2

из условия выходит, что 1,6,11,16... карт - белая, 2,7,12,17 - ж и т.д

всего карточек - 5, чтобы найти, какого цвета карточка нужно номер поделить на 5 и посмотреть остаток, если 1 - белая, 2 - желтая, 3 - зеленая , 4 - красная, 0 - синия

24:5= 4 (4 - ост.) красная карточка 

38:5=7 (3 ост.) зеленая карточка

10:5=2 (ост. 0) синяя карточка

Answer 3

Task Analysis

The teacher has prepared 42 cards of five different colors for a test. The cards are arranged in a specific sequence and numbered from 1 to 42. The task is to determine the color of the cards with the numbers 24, 38, and 10, as well as the color of the last card.

Solution

To solve this, we need to determine the pattern of the sequence and then find the colors of the cards with the specified numbers.

Sequence Pattern

The sequence of colors is: б, ж, з, к, с, б, ж, ...

Determining the Colors

To find the color of the card with a specific number, we can use the sequence pattern to determine the color at that position.

1. Color of the Card with Number 24: - To find the color of the card with number 24, we need to determine the position of the 24th card in the sequence and then find the corresponding color.

2. Color of the Card with Number 38: - Similarly, we'll determine the position of the 38th card in the sequence and find its color.

3. Color of the Card with Number 10: - We'll do the same for the 10th card.

4. Color of the Last Card: - Finally, we'll determine the color of the last card in the sequence.

Let's calculate the positions and colors of the specified cards.

Calculating Positions and Colors

The sequence pattern is: б, ж, з, к, с, б, ж, ...

1. Color of the Card with Number 24: - The 24th card in the sequence is the color синего.

2. Color of the Card with Number 38: - The 38th card in the sequence is the color жёлтого.

3. Color of the Card with Number 10: - The 10th card in the sequence is the color жёлтого.

4. Color of the Last Card: - The last card in the sequence is the color синего.

Conclusion

The color of the card with number 24 is синего, the color of the card with number 38 is жёлтого, the color of the card with number 10 is жёлтого, and the color of the last card is синего.
