1. Problem Description

The problem asks us to find the 2024th number in the arithmetic sequence 2, 5, 8, 11, 14, ...

2. Solution Steps

The given sequence is an arithmetic sequence. We need to find the 2024th term of the sequence.
First, we find the common difference dd between consecutive terms:
d=52=3d = 5 - 2 = 3
The first term is a1=2a_1 = 2.
The formula for the nth term of an arithmetic sequence is:
an=a1+(n1)da_n = a_1 + (n - 1)d
We want to find a2024a_{2024}, so we substitute n=2024n = 2024, a1=2a_1 = 2, and d=3d = 3 into the formula:
a2024=2+(20241)×3a_{2024} = 2 + (2024 - 1) \times 3
a2024=2+(2023)×3a_{2024} = 2 + (2023) \times 3
a2024=2+6069a_{2024} = 2 + 6069
a2024=6071a_{2024} = 6071

3. Final Answer

The 2024th number in the sequence is
6
0
7

1. Answer: B. 6071
