18.
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, 11, 12, 15...............

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.
-27 You subtract powers of 2 everytime... 1,2,4,8,16
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 next term is -2.
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
