Question

Write the first two terms of the sequence whose nth term is t_n = 3n ‒ 4.

Answer 1

The general formula for the nth term of an arithmetic progression (A.P.) is given by:

t_n = 3n – 4

For n = 1,

t₁ = 3 × 1 – 4

= 3 – 4

= –1

For n = 2,

t₂ = 3 × 2 – 4

= 6 – 4

= 2

Hence, the first two terms of the sequence are –1 and 2.
