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.
18 b/c the pattern is +1,+2,+3...
0 + 2 + 3 = 5 2 + 3 + 5 = 10 3 + 5 + 10 = 18 5 + 10 + 18 = 33
18
The rule for this sequence appears to be adding consecutive prime numbers. The sequence starts with 3, then adds the next prime number 2 to get 4. It then adds 3 (the next prime number) to 4 to get 7, then 5 to 7 to get 12, and so on. Each number in the sequence is the sum of the previous number and the next prime number in order.
