How do you find the arithmetic means of the sequence -8, __, __, __, __, 7?
For problems like these, we have to ask ourselves "How many times do I have to add the common difference,
To answer, put a "+d" between -8 and the first space, between the first space and the second space, continuing until you add a d between the last space and the
In the end, you should have
We can set up the following equation:
I'm assuming that by arithmetic means you mean average, or mean, of the whole sequence.
Hence, the mean of the numbers in the sequence is
Hopefully this helps!
