Question

3 , 6, ?,15,21 5,9,?,23,33

Answer 1

Ответ:

3,6,12,15,21

5,9,19.23,33

Answer 2

It seems like you have provided three sequences of numbers and are looking for the missing numbers in each sequence. Let's analyze each sequence:

1. 3, 6, ?, 15, 21: The pattern here seems to be an increment of 3, then an increment of 6, and so on. So, the missing number could be obtained by adding 9 to the previous number (6). Thus, the missing number is 6 + 9 = 15.

2. 5, 9, ?, 23, 33: Similarly, the pattern here could involve adding an incrementing sequence of numbers: 4, 5, 6, ... The missing number can be obtained by adding 6 to the previous number (9). Thus, the missing number is 9 + 6 = 15.

Therefore, the missing numbers in the sequences are 15 and 15 respectively.
