<span>The pattern being formed is such that the number before the plus sign is being multipled to the sum of the number after the plus sign and 1. For example, 1 * (4 + 1) = 5. 2 * (5 + 1) = 12. 3 * (6 + 1) = 21.
Applying the same principle for the given question, 8 * (11 + 1) = 8 * 12 = 96.Hope this helps. Let me know if you need additional help!</span>
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
