Final answer:
The missing number in the sequence is 31.
Step-by-step explanation:
The missing number in the sequence is 31.
To find the missing number, we need to observe the pattern in the given sequence. We can see that the difference between consecutive numbers is increasing by 10 each time. Starting from the first number, 1, we add 10 to get the next number, 11. Continuing this pattern, we add 10 to the previous number to get the next number, until we reach the missing number, 31. After that, we add 10 to 31 to get the last number, 41.
Therefore, the missing number in the sequence is 31.
