Math Problem Statement

X1=2024 dan xn=n/2xn-1 untuk bilangan n>1 hasil dari 2024πi=1×i

Solution

To solve this problem, let's start by understanding the recursive formula provided and the expression 2024i=1ni2024 \prod_{i=1}^n i.

Understanding the Recursive Formula

Given:

  • x1=2024x_1 = 2024
  • xn=n2xn1x_n = \frac{n}{2} x_{n-1} for n>1n > 1

This recursive relation shows that each term xnx_n is calculated based on the previous term xn1x_{n-1}, multiplied by n2\frac{n}{2}.

Calculating the General Expression for xnx_n

Let's compute the first few values to identify a pattern:

x_1 &= 2024, \\ x_2 &= \frac{2}{2} x_1 = 1 \times 2024 = 2024, \\ x_3 &= \frac{3}{2} x_2 = \frac{3}{2} \times 2024 = 3036, \\ x_4 &= \frac{4}{2} x_3 = 2 \times 3036 = 6072, \\ x_5 &= \frac{5}{2} x_4 = \frac{5}{2} \times 6072 = 15180. \end{align*}$$ We see that the formula indeed builds upon the previous term multiplied by $$\frac{n}{2}$$. ### Expression $$2024 \prod_{i=1}^n i$$ The expression $$2024 \prod_{i=1}^n i$$ involves multiplying 2024 by the product of all integers from 1 to $$n$$. This can be written as: $$2024 \times (1 \times 2 \times 3 \times \ldots \times n) = 2024 \times n!.$$ This shows that the expression is 2024 multiplied by the factorial of $$n$$. ### Conclusion The result for $$x_n$$ in terms of the recursive formula involves repeatedly applying the multiplication by $$\frac{n}{2}$$, and the expression $$2024 \prod_{i=1}^n i$$ is equal to $$2024 \times n!$$. ### Follow-up Questions: 1. Do you want to find the value of $$x_n$$ for a specific $$n$$? 2. Are you interested in the derivation of a closed formula for $$x_n$$? 3. Would you like to explore how factorial growth impacts the values of $$x_n$$? 4. Do you want to understand the convergence properties of this sequence? 5. Would you like to see the computation of $$x_n$$ for higher values of $$n$$? #### Tip: When dealing with recursive sequences, try calculating the first few terms to identify patterns that can help generalize the formula!
