Math Problem Statement

n cubed write 3 terms in these sequences with an nth term

Solution

If the nth term of a sequence is given by n3n^3, we can generate the terms by substituting values for nn. Here, I'll calculate the first three terms of the sequence where each term is the cube of nn.

Calculation of the First Three Terms:

  1. For n=1n = 1: a1=13=1a_1 = 1^3 = 1

  2. For n=2n = 2: a2=23=8a_2 = 2^3 = 8

  3. For n=3n = 3: a3=33=27a_3 = 3^3 = 27

First Three Terms of the Sequence

The first three terms in this sequence are: 1,8,271, 8, 27

This sequence, defined by n3n^3, grows quickly as nn increases.

Would you like further details on this sequence or have any other questions?

Here are five related questions to explore:

  1. What would the 4th term of this sequence be?
  2. How does the sequence defined by n3n^3 differ from the sequence defined by n2n^2?
  3. What pattern do you notice in the differences between consecutive terms of this sequence?
  4. How can we express the sum of the first three terms of the sequence?
  5. How does n3n^3 relate to the volume of a cube with side length nn?

Tip: Sequences defined by powers of nn, like n2n^2 or n3n^3, grow faster than linear sequences, providing a good way to explore exponential growth.
