These are Fibannoci's numbers. Therefore, the 7th number is 21.
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
13, because if you add the last number to the current number you get the next number
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)
Every next number is increased by 5. The next number in the sequence is 23.
18
The sequence alternates between a number and that number plus one. After 2 comes 3, after 3 comes 12, after 12 comes 13, after 13 comes 52, and after 52 comes 53. Following this pattern, the next number after 53 would be 212, as it follows 52 multiplied by 4 (the previous non-incrementing number). Therefore, the next number in the sequence is 212.
The answer is 34. The full sequence is called the Fibonachi series. Your sequence is 3 5 8 13 21 3 + 5= 8 8 + 13 = 21 Therefore: 13 + 21 = 34
These are Fibannoci's numbers. Therefore, the 7th number is 21.
18. 3+1=4, 4+2=6, 6+3=9, 9+4=13, 13+5=18.
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
13, because if you add the last number to the current number you get the next number

183 + 1 = 44 + 2 = 66 + 3 = 99 + 4 = 13Etc. The next number in the sequence would be 18, then 25, and so on.Ans 2.The previous answer contains an error.The next number in the sequence would be 18 (13 + 5),after which comes 24 (18 + 6 ) not 25.
3,5,8,13 is followed by 21. 1,1,2,3,5,8,13,21,34,55,... is the Fibonacci series or Fibonacci sequence where the next number in the sequence is the sum of the last two numbers (1+1=2, 1+2=3, 2+3=5, etc.)
