Question

A sequence of digits has the property that each pair of successive digits, taken in the order written, forms a decimal numeral representing a multiple of either 1717 or 2323. If the first digit is 99 and the sequence is finite, what is its last (possible) digit

Answer 1

Answer:

Concept: Mathematical Sequences

1. Let An be 99 a double digit multiple
2. The sequence is finite.
3. Finite= restricted and not bounded to positive infinity
4. By that logic the last possible digit is 999999999999999999999999999999999999999999999
