100,121,105,113,108,x; mean 112

you are right.

yeah its the question i need to know what the x is if the mean is 112

oh i thought you meant that x stands for 112

nope

To find the missing value in the sequence 100, 121, 105, 113, 108, x, given that the mean is 112, we can follow a few simple steps:

Step 1: Add up all the known values in the sequence.
100 + 121 + 105 + 113 + 108 = 547

Step 2: Determine the number of values in the sequence (including the missing value).
In this case, we have 6 values, so we divide the sum from Step 1 by 6 to find the mean.
547 / 6 = 91.1667

Step 3: Calculate the missing value using the mean.
To find the missing value, we need the sum of all the values (including the missing value) to be equal to the mean (112) multiplied by the number of values (6). So we set up the equation:
(547 + x) / 6 = 112

Step 4: Solve the equation for x.
Multiply both sides of the equation by 6 to remove the denominator:
547 + x = 112 * 6
547 + x = 672
Subtract 547 from both sides of the equation to isolate x on one side:
x = 672 - 547
x = 125

Therefore, the missing value in the sequence is 125.
