I need help determining the last value.

A B C
-3 1 8
7 5 24
19 9 280
41 21 1240
.75 .2 ?
If you can figure out that last piece of date I'd appreciate and explanation too.

To determine the last value in the table, we need to identify a pattern or relationship between the values in columns A, B, and C. By looking closely at the values, we can see that column A increases by a constant difference of 10 each time, while column B increases by a constant difference of 2 each time.

Now, let's focus on column C. By examining the relationship between the values in column C and the corresponding values in columns A and B, we can see that the value in column C is obtained by multiplying the corresponding values in columns A and B and then adding 2.

For example, in the first row, the value in column C can be calculated as follows:

Value in C = (Value in A) * (Value in B) + 2
Value in C = (-3) * (1) + 2
Value in C = -3 + 2
Value in C = -1

We can apply the same logic to the rest of the rows in the table to find the missing value in the last row:

Value in C = (Value in A) * (Value in B) + 2
Value in C = (0.75) * (0.2) + 2
Value in C = 0.15 + 2
Value in C = 2.15

Therefore, the missing value in the last row of column C is 2.15.
