Q. 1 A

Write the first three terms of the following sequences defined by:

tn = 3n + 1

Answer :

Given: tn = 3n + 1


Taking n = 1, we get


t1 = 3(1) + 1 = 3 + 1 = 4


Taking n = 2, we get


t2 = 3(2) + 1 = 6 + 1 = 7


Taking n = 3, we get


t3 = 3(3) + 1 = 9 + 1 = 10


Hence, the first three terms are 4, 7 and 10.
