Question

Write a rule for the sequence and find the missing term. 2 5/12, 4 2/12, 1 11/12, _____, 1 5/12


(In math)

Answer 1

This is an arithmetic sequence, with each term decreasing by the previous term by a constant amount d

Subtract the second term - first term, or (4 2/12) - (2 5/12) to find the value of d

Then, to find the term after 1 11/12, simply add 1 11/12 + d
