Question

В магазине составляли букеты из цветов, первый букет состоял из 3 цветов, второй из 7 цветов, третий из 11 цветов и т.д. Сколько цветов понадобится для составления 7 букетов. СРОЧНОООООООО!!!​

Answer 1

Ответ:

105 цветов

Объяснение:

К каждому букету прибавляется +4, посчитаем:

3+(3+4)+(3+4+4)+(3+4+4+4)+(3+4+4+4+4)+(3+4+4+4+4+4)+(3+4+4+4+4+4+4)=105

Answer 2

Calculating the Total Number of Flowers Needed for 7 Bouquets

To calculate the total number of flowers needed for 7 bouquets, we can observe a pattern in the number of flowers used for each consecutive bouquet.

- The first bouquet consists of 3 flowers. - The second bouquet consists of 7 flowers. - The third bouquet consists of 11 flowers.

We can see that the number of flowers for each bouquet increases by 4 compared to the previous one. This forms an arithmetic sequence with a common difference of 4.

To find the number of flowers needed for the 7th bouquet, we can use the formula for the nth term of an arithmetic sequence:

nth term = a + (n - 1)d

Where: - a = the first term of the sequence - n = the term number - d = the common difference

Using this formula, we can calculate the number of flowers needed for the 7th bouquet:

a = 3 (first bouquet) n = 7 (7th bouquet) d = 4 (common difference)

Plugging these values into the formula: nth term = 3 + (7 - 1) * 4 nth term = 3 + 6 * 4 nth term = 3 + 24 nth term = 27

So, the 7th bouquet would consist of 27 flowers.

Therefore, to create 7 bouquets, the total number of flowers needed would be: 3 + 7 + 11 + 15 + 19 + 23 + 27 = 105 flowers.
