Write the first five terms of the sequence an = 3n + 1.
Solution:
Given,
Sequence an = 3n + 1.
To obtain the first five terms, substitute n = 1, 2, 3, 4, 5.
a1 = (3 × 1) + 1 = 3 + 1 = 4
a2 = (3 × 2) + 1 = 6 + 1 = 7
a3 = (3 × 3) + 1 = 9 + 1 = 10
a4 = (3 × 4) + 1 = 12 + 1 = 13
a5 = (3 × 5) + 1 = 15 + 1 = 16.
Therefore, the first five terms are 4, 7, 10, 13, 16.
Write the first five terms of the sequence an = 3n + 1.
Summary:
The first five terms of the sequence an = 3n + 1 is 4, 7, 10, 13, 16.
