Which recursive formula can be used to define this sequence for n > 1?15,28,41,54,67,80,…Choices:(A)an=an−1+13(B)an=131an−1(C)an=1427an−1(D)an=an−1+an−1−13
Q. Which recursive formula can be used to define this sequence for n>1?15,28,41,54,67,80,…Choices:(A)an=an−1+13(B)an=131an−1(C)an=1427an−1(D)an=an−1+an−1−13
Sequence Type: We have the sequence: 15,28,41,54,67,80,…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 two consecutive terms.For example, take the second term and subtract the first term: 28−15=13Common difference (d): 13
Recursive Formula: Identify the recursive formula for the given sequence.Since the sequence is arithmetic, the recursive formula will have the form an=an−1+d.Substitute 13 for d in the formula.Recursive formula: an=an−1+13
Match Formula with Choices: Match the recursive formula with the given choices.The correct choice that matches the formula an=an−1+13 is:(A) a=a+13However, this choice is not correctly written. It should be an=an−1+13, not a=a+13.
