How do u find the nth term
WebHow do we find the nth term? The sum of an arithmetic series is found by multiplying the number of terms times the average of the first and last terms. Example: 3 + 7 + 11 + 15 + ··· + 99 has a 1 = 3 and d = 4. To find n, use the explicit formula for an arithmetic sequence . WebTo find the sum for arithmetic sequence, sn= n(n+1)/2, it is shown (n+1)/2, can be replaced with the average of nth term and first term. How do we understand that we should not replace the "n" outside the bracket should …

WebIn Mathematics, an arithmetic progression (AP) is defined as the list or sequence of numbers, in which each term in the sequence is obtained by adding a fixed number to the preceding term. The fixed number is called the common difference of the arithmetic progression. The fixed number can be positive or negative or zero. WebThe a(n-1) is the term right before the last term. e.g.: If we have a sum of terms, it would look something like this; a1 (first term) + a2 (second term) + .... (all in between) + a(n-1) (term right before last or nth term) + an (last term/nth term). Hope this helps, - …
