Find the first five terms of the following sequences, whose ‘nth’ terms are given: v. tn = n^3

Question

Find the first five terms of the following sequence, whose ‘n^th’ terms are given:

t_n = n³

Answer 1

Given, t_n = n³

For n = 1, t₁ = (1)³ = 1

For n = 2, t₂ = (2)³ = 8

For n = 3, t₃ = (3)³ = 27

For n = 4, t₄ = (4)³ = 64

For n = 5, t₅ = (5)³ = 125

\(\therefore\) The first five terms are 1, 8, 27, 64 and 125.
