Question

find the nth term of the given sequences, 3,4,5,6,7
the first 5 terms of the sequence are 1,2,3,4,5

Answer 1

the series is in a.p

so, the formula is =.

tn = a1 + (n - 1) × d

here, a1 = 1

tn = n th term

d = (a3 - a2) = 3-2 = 1

so, tn = 1 + (n- 1)×1

tn = 1 + n - 1

tn = n

so, the nth term is n
