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 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 next figure would be 21, followed by 11 & 10.
The answer is 15 because the pattern is subtract one, add two
11
11
11.
11, -10, 9
It would be 6. The pattern is -divide by 2 add 2 add 3- repeat.

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
