Page 1: Solving Sequence Problems
This page presents a detailed examination of ciągi zadania maturalne PDF, focusing on solving equations to determine if given numbers are terms in specific sequences.
The problem involves a sequence with the general term an = 4n + 2 / 16 - n. Students are tasked with identifying which of the given numbers 30,9,5,46 are terms in this sequence.
Definition: A sequence term is a number that satisfies the general formula of the sequence for some integer value of n.
The solution process involves:
- Setting up equations using the general term formula and the given numbers.
- Solving these equations to find the value of n.
- Checking if the resulting n is a positive integer.
Example: For 30, the equation is 3016−n = 4n+2, which simplifies to -66n = -726. Solving this gives n = 11, confirming 30 is a term in the sequence.
Highlight: It's crucial to verify that the calculated n is a positive integer. If n is not an integer or is negative, the number is not a term in the sequence.
The page also shows detailed calculations for other numbers:
- For 9: 916−n = 4n+2, leading to n = 15
- For 46: 4616−n = 4n+2, resulting in n ≈ 11.03 notaninteger,thusnotaterm
- For 30: Calculation confirms it's a term n=7
Vocabulary: "Wyraz ciągu" means "term of the sequence" in Polish.
