Given:
Sequence whose general term is tn =(-1)^n / 3+n
To Find:
First three terms
Solution:
ATQ
tn =(-1)^n / 3+n
We need to find t1 , t2 and t3
t1 =(-1)^1 / 3+1
t1 = -1/4
t2 =(-1)^2 / 3+2
t2 = 1/5
t3 =(-1)^3 / 3+3
t3 = -1/6
Hence, first three terms of the given sequence are -1/4 , 1/5 and -1/6 respectively.
