Sequences: The Method of Common Differences
Sequences: The Method of Common Differences

Then a = ,1,, b = 0, and c = ,1,, so the ,formula, is: 1n 2 + 0n + ,1, = n 2 + ,1,...just as I had determined before, and the sixth term is: next term: 6 2 + ,1, = 36 + ,1, = 37 ,formula, for the n-th term: n 2 + ,1,. You can simplify your computations somewhat by using a ,formula, for the leading coefficient of the ,sequence's, …

Sigma Notation | Sequences and Series
Sigma Notation | Sequences and Series

Sigma notation is a very useful and compact notation for writing the sum of a given number of terms of a ,sequence,. A sum may be written out using the summation symbol \(\sum\) (Sigma), which is the capital letter “S” in the Greek alphabet. It indicates that you must sum the expression to the right of the summation symbol:

To generate a member of the sequence from the previous member, read off the digits of the previous member, counting the number of digits in groups of the same digit. For example: 1 is read off as "one 1" or 11. 11 is read off as "two 1s" or 21. 21 is read off as "one 2, then one 1" or 1211. 1211 is read off as "one 1, one 2, then two 1s" or 111221. 111221 is read off as "three 1s, two 2s, then one 1" or 312211.
