WebWhen dealing with a sum, you have a sequence that generates the terms. In this case, you have the sequence an = (3 2)n Which means that n -th term is generates by raising 3 2 to the n -th power. Moreover, the n -th partial sum means to sum the first n terms from the sequence. So, in your case, you're looking for a1 + a2 +a3 + a4, which means WebOct 18, 2024 · A partial sum of an infinite series is a finite sum of the form. k ∑ n = 1an = a1 + a2 + a3 + ⋯ + ak.
