1+3=4
3+4=7
4+7=11
7+11=18
-27 You subtract powers of 2 everytime... 1,2,4,8,16
42 as you have to add the next prime number onto the previous value.
42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
It is: 47 because 18+29 = 47
8
8, 11, 12, 15...............
14
11 comes next.
1+1=2 2+2=4 3+4=7 4+7=11 Your answer is 11
-11 Pattern: Subtract 1, subtract 2, subtract 3 and so on.

It's a pattern of odd numbers- so... nine is next, then eleven, and so on. 1-3-5-7-9-11....
42 as you have to add the next prime number onto the previous value.
1 , 2, 4, 7, 11 +1,+2,+3,+4
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.
42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
The next term is -2.
