Answer:

First five terms = 0, 1/4, 1/2, 3/4, and 1

Explanation:

The formula for the nth term of an arithmetic sequence is given by:

an = a1 + (n - 1)d, where

  • a1 is the first term,
  • n is the term position (e.g., 1st, 5th, etc.),
  • and d is the common difference.

We're already given the first term (a1 = 0), so we simply need to find the next four terms.

Thus, to find these next four terms, we substitute 0 for a1 and 1/4 for d each time. For n, we substitute the term position for n (e.g., 2 for the 2nd, 3 for the 3rd term, etc.)

2nd term:

an = 0 + (2 - 1)(1/4)

an = (1)(1/4)

an = 1/4

Thus, the 2nd term is 1/4.

3rd term:

an = 0 + (3 - 1)(1/4)

an = (2)(1/4)

an = 2/4

an = 1/2

Thus, the 3rd term is 1/2.

4th term:

an = 0 + (4 - 1)(1/4)

an = (3)(1/4)

an = 3/4

Thus, the 4th term is 3/4.

5th term:

an = 0 + (5 - 1)(1/4)

an = (4)(1/4)

an = 4/4

an = 1

Thus, the 5th term is 1.

Writing the first 5 terms:

Therefore, the first five terms of the sequence are 0, 1/4, 1/2, 3/4, and 1.
