Answer 2

Ответ:

В)27

Пошаговое объяснение:

потому что 2+3=5

5+4=9

9+5=14

14+6=20

20+7=27

Answer 3

To find the pattern in the given sequence (2, 5, 9, 14, 20), let's calculate the differences between consecutive terms:

5 - 2 = 3 9 - 5 = 4 14 - 9 = 5 20 - 14 = 6

Notice that the differences themselves form a sequence (3, 4, 5, 6). This sequence represents the increments between each term in the original sequence.

To find the next difference, we add 1 to the last difference: 6 + 1 = 7

Now, let's calculate the next term in the original sequence: 20 + 7 = 27

Therefore, the missing term in the sequence (2, 5, 9, 14, 20, ?) is 27.

Hence, the correct answer is B) 27.
