Which recursive formula can be used to define this sequence for n > 1?9,13,17,21,25,29,…Choices:(A) an=an−1+an−2−4(B) an=an−1+4(C) an=4an−1(D) an=913an−1
Q. Which recursive formula can be used to define this sequence for n>1?9,13,17,21,25,29,…Choices:(A) an=an−1+an−2−4(B) an=an−1+4(C) an=4an−1(D) an=913an−1
Sequence Type: We have the sequence: 9,13,17,21,25,29,…Is the given sequence geometric or arithmetic?The difference between consecutive terms is the same.The given sequence is arithmetic.
Find Common Difference: Find the common difference, d, by subtracting any term from the term that follows it.For example, take the first two terms: 13 and 9.13−9=4Common difference (d): 4
Recursive Formula: Identify the recursive formula for the given sequence.Since the common difference is 4, the recursive formula will involve adding 4 to the previous term.The correct recursive formula is: an=a(n−1)+4
Match with Choices: Match the correct recursive formula with the given choices.The correct formula, an=an−1+4, corresponds to choice (B).
