Contact Author What Is a Sequence?
We will use the formula for the sum of the first n terms of an arithmetic sequence,to help us with this problem. Usually, the formula for the nth term of an arithmetic sequence whose first term is a1 and whose common difference is d is displayed below.
If you said 3 you are right! A free online version of Octave is available at Octave Online. Could you show how you did as well, I would appreciate it.
Basically we need to find three things: the first term of the sequence, the last term of the sequence, and how many terms of the sequence we are adding in the series. The denotation for the terms in a sequence is: a1, a2, a3, a4, an.
October 18th,PM. If you start at 1 and go all the way to 20, there will be 20 terms.
Continue to take the differences of the differences three times total, at which point all the differences should be equal. Trivial Solution We can easily see that this is an A. Question: Write down an expression, in terms of n, for the nth term of this sequence.
Note how n starts at 5 and ends at
