Find the first five terms of the following sequence, whose ‘nth’ t

1.	Find the first five terms of the following sequence, whose ‘nth’ terms are given:tn = n3
Answer» 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.

Find the first five terms of the following sequence, whose ‘nth’ terms are given:tn = n3

Answer»

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.
