1, 2, 3, ? , 99 :: find out the missing number?
To find the missing number in the given sequence (1, 2, 3, ?, 99), we can look for a pattern or rule that governs the sequence.
One logical pattern we can observe in this sequence is that each number is incrementing by 1. Based on this pattern, we can assume that the missing number should also be incremented by 1 from the previous number.
Therefore, to find the missing number, we can add 1 to the previous number in the sequence. In this case, the previous number is 3. Adding 1 to 3 gives us 4.
So, the missing number in the given sequence is 4.
