Final answer:
To find the missing number in the sequence, calculate the sum of all the numbers in the sequence and subtract the sum of the known numbers from it. The missing number is 124.
Step-by-step explanation:
To find the value of the missing number in the given sequence, we can start by finding the sum of all the numbers in the sequence by multiplying the mean by the total number of elements. In this case, the mean is 130 and there are 5 total elements. So, the sum of all the numbers is 130 * 5 = 650.
Next, we subtract the sum of the known numbers (104 + 137 + 154 + 131) from the total sum to find the missing number: 650 - (104 + 137 + 154 + 131) = 124.
Therefore, the value of the missing number (represented by x) is 124.
