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, - … WebThe n -th term of an arithmetic sequence is of the form an = a + (n − 1)d. In this case, that formula gives me a_6 = a + (6 - 1)\left (\frac {3} {2}\right) = 5 a6 = a+(6−1)(23) = 5. Solving this formula for the value of the first term of the sequence, I get a = -\frac {5} {2} −25. Then: a1 = -\frac {5} {2} −25

How do you find the nth term of a geometric sequence?

Webfor y's, the first term is y and the common difference is 0 since every term is the same. for x's, the first term is 0 and the common difference is x since every term increases by one x. to sum n terms of an arithmetic progression you need the first and last term, average them out and multiply by the total number of terms n. WebTo find the next few terms in an arithmetic sequence, you first need to find the common difference, the constant amount of change between numbers in an arithmetic sequence. … hifi nn library
