The arithmetic sequence is .
Find the common difference by subtracting successive terms.
\The common difference is 9.
\Add 9 to last term of the sequence to get the next termin the sequence.
\Continue adding 9 untill the next three terms are found.
\\
–4 + 9 = 5, 5 + 9 = 14 and 14 + 9 = 23.
The next three terms are 5, 14, 23.
