The pattern in the sequence 11 12 14 17 21 is an increasing sequence where each number is the sum of the previous number and a specific value. In this case, the specific value is increasing by 1 with each subsequent number. So, starting from 11, we add 1 to get 12, then add 2 to get 14, add 3 to get 17, and add 4 to get 21.
The sequence 12, 13, 14, 15 is an arithmetic sequence where each term increases by 1. The nth term can be expressed as ( a_n = 12 + (n - 1) \times 1 ), which simplifies to ( a_n = 11 + n ). Therefore, the nth term of the sequence is ( a_n = n + 11 ).
11, -10, 9
The sequence appears to involve two alternating patterns: one decreasing by 1 (15 to 14) and then by 2 (14 to 12), while the last number, 50, seems unrelated to the first three. If we focus on the decreasing pattern, the next number would likely be 11. However, without additional context for the 50, it's unclear how it fits into the sequence. Thus, a possible continuation could be 11 followed by another unrelated number or pattern.
The sequence alternates between two patterns: one decreasing by 3 and the other increasing by 1. Following this pattern, the next number after 14 would be 11 (14 - 3). Then, the number after that would be 15 (11 + 1). Thus, the next two numbers are 11 and 15.
It is 30; the first, third, and fifth numbers form the sequence 12, 18, 24. The second, fourth, and sixth numbers follow the sequence 11, 14, 17. Logically, the seventh number must be 24 + 6, so 30.
The answer is 15 because the pattern is subtract one, add two
11
11.
11
The sequence 12, 13, 14, 15 is an arithmetic sequence where each term increases by 1. The nth term can be expressed as ( a_n = 12 + (n - 1) \times 1 ), which simplifies to ( a_n = 11 + n ). Therefore, the nth term of the sequence is ( a_n = n + 11 ).

It would be 6. The pattern is -divide by 2 add 2 add 3- repeat.
The sequence alternates between two patterns: one decreasing by 3 and the other increasing by 1. Following this pattern, the next number after 14 would be 11 (14 - 3). Then, the number after that would be 15 (11 + 1). Thus, the next two numbers are 11 and 15.
12 11 18 14 24 17 30 20.. i think ;-) pattern: 18-12 = 6 14-11 = 3 24-18 = 6 17-14 = 3 i hope that helps.
18 9 11 14 7 9 12 the series is like 18/2= 9 9+2=11 11+3=14 14/2=7 7+2=9 9+3=12 so next number will be.. 12/2=6 then 6+2=8 8+3=11
17?
Think it's 30...then 20
