Question

Write a recursive formula for the given sequence. 47, 39, 31, 23, 15, ....

hintHint:

  • Recursive Formula is a formula that defines the each term of sequence using the previous/preceding terms.

The correct answer is: a_n=a_(n-1)-8.


    Explanation:
    • We have given a sequence 47,39,31,23,15,...
    • We have to find the recursive formula.
    Step 1 of 1:
    We have given a sequence 47, 39, 31, 23, 15, ....
    The given sequence is an AP.
    We know that the recursive formula for any AP is a subscript n equals a subscript n minus 1 end subscript plus d, where d is common difference.
    Here the common difference is - 8
    So, The recursive formula is

    a subscript n equals a subscript n minus 1 end subscript plus d

    a subscript n equals a subscript n minus 1 end subscript minus 8
