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=...
Step 1: Identify the nth term of the sequence Let's denote the nth term of the sequence asTn. We observe the sequence: -T1=1 -T2=4 -T3=13 -T4=40 -T5=121 Step 2: Find the pattern in the sequence To find a pattern, we can look at the differences between consecutive terms: ...

Find the first six terms of the sequence. {eq}a_1 = -1, a_n = 2 \cdot a_{n - 1} {/eq} Recursive Sequence: A sequence is said to be a recursive sequence if we can calculate the next term of the sequence only if we know its previous terms. In simple langua...
8. Here are some sequences that are not linear nor quadratic. Find the next 3 terms in each sequence by finding patterns.(a) {1,3,9,27,81,243,...}(b) {4,5,9,14,23,37,...}(c){1,8,27,64,125,216,...}(d) {1,7,21,46,85,141,...} ...
When this set of numbers follow a particular pattern then set of numbers are in sequence. This sequence may be finite or infinite. Now, the nth term of this sequence is called general term and from this term, we can find any terms of that sequence....
