377 - 144 = 233 and 233 / 2 = 116.5 is the common difference so the 11th term is 260.5

Answer:
You have to know the basic properties of exponents.
Jill's answer is wrong because you add the powers when there are like bases. You don't multiply.
-3+6=3
The base stays the same.
7 9/12 = 7.75
2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8
2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.
