After you have learned to solve problems with arithmetic and quadratic sequences, you may be asked to solve problems with cubic sequences. As the name implies, cubic sequences rely on powers no higher than 3 to find the next term in the sequence. Dependi
a_2-a_1=5-(5+k) or -k find the difference between pairs of consecutive termsa_3-a_2=5-k-5 or -k to verify the common difference.The common difference is -k.Add -k to the third term to get the fourth term, and so on.a_4=5-k-k or 5-2ka_5=5-2k-k or 5-3ka_6=...
