Write the first two terms of the sequence whose nth term is tn = 3n ‒ 4.
Find the first term of the given sequence:
tn = 3n ‒ 4
उत्तर
The general formula for the nth term of an arithmetic progression (A.P.) is given by:
tn = 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.
