Find the missing term in each sequence. Homework Help ✎
Hint: This is an arithmetic sequence.
Notice that the table skips many of the terms. An equation of the form t(n) = mn + t(0) needs to be written.
Think of the sequence as a function with the points (1, 1) and (5, −7). Use these points to find m.
Use m to calculate t(0).
Write your equation.
Let n = 23 in your equation to find t(23).
Is this sequence arithmetic or geometric?
Use the pattern in the table to find the 4th term.
