Use benchmarks to estimate the sum, difference, or product.
3. 15/16 1/6
a. 3
b. 1 1/2
c. 2
d. 1

My opinion is d/1 okay and i did not understand

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
