Q1 of 176 Page 9

Write the first three terms of the following sequences defined by:
t_n = n² + 1

Given: t_n = n² + 1

Taking n = 1, we get

t₁ = (1)² + 1 = 1 + 1 = 2

Taking n = 2, we get

t₂ = (2)² + 1 = 4 + 1 = 5

Taking n = 3, we get

t₃ = (3)² + 1 = 9 + 1 = 10

Hence, the first three terms are 2, 5 and 10.

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

t_n = 3n + 1

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

t_n = n(n + 2)

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

t_n = 2n+5

Write the first three terms of the following sequences defined by:tn = n2 + 1
