Find a formula for the general term of the sequence:2, 6, 12, 20, 30... |
|
Answer» The formula for the general term of the sequence:2, 6, 12, 20, 30... is \(a_{n}\) = n2+ n. Progressions are sequences that follow a common pattern in theirterms. We can obtain the formula for the nth or the general term and for the sum till the nthterm if we find the pattern in any sequence. |
