Q. Which recursive formula can be used to define this sequence for n>1?1,4,7,10,13,16,…Choices:(A)an=an−1+an−2−3(B)an=4an−1(C)an=an−1−3(D)an=an−1+3
Sequence Type: We have the sequence: 1,4,7,10,13,16,…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.Two consecutive terms are 1 and 4.4−1=3Common difference (d): 3
Recursive Formula: Identify the recursive formula for the given sequence.Substitute 3 for d in an=an−1+d.Recursive formula: an=an−1+3
Match with Choices: Match the recursive formula with the given choices.The correct choice is (D)an=a(n−1)+3.
