Question 1040094: The 3rd term of an arithmetic sequence is 12 and its 7th term is 32, what is its 11th term?

For an arithmetic sequence, each distance is equal.
From the third term to the seventh is 4 terms and it increased 20. Therefore the common difference is 4.
For the 11th term, four terms above 7, the value will be 20 more than 32, or 52.
