What does “barisan bilangan real a1,a2,a3,… memenuhi an=2-3” mean?

Answer: “Barisan bilangan real a1,a2,a3,… memenuhi an=2-3” refers to a sequence of real numbers where each term in the sequence, denoted as a_n, is given by the formula a_n = 2 - 3.

Let’s break this down:

  1. Sequence Definition:

    • The sequence a_1, a_2, a_3, \ldots represents an ordered list of real numbers.

  2. Formula a_n = 2 - 3:

    • This formula states that each term a_n in the sequence can be obtained by substituting n into the expression 2 - 3.
    • Simplifying 2 - 3 gives us -1.

  3. Constant Sequence:

    • Since the expression 2 - 3 is a constant, every term in the sequence is -1.
    • Thus, the sequence is -1, -1, -1, \ldots.

Summary: The sequence defined by a_n = 2 - 3 is a constant sequence where every term is -1.
