  1. Answer:

    he first two terms are any positive whole numbers.

    • Each of the remaining terms is the sum of the digits of the previous

    two terms.

    For example, starting with 5 and 8 the Diginacci sequence is

    5, 8, 13, 12, 7, 10,. . .

    The calculations for this example are

    5 + 8 = 13, 8 + 1 + 3 = 12, 1+ 3 +1+ 2 = 7, 1 + 2 + 7 = 10.

    a) List the first 26 terms of the Diginacci sequence above.

    b) Find, with explanation, two starting terms for a Diginacci sequence

    so that its 2021st term is 11.

    c) Find, with explanation, a Diginacci sequence that has no term equal

    to 11.

    d) Find, with explanation, a sequence with two different starting terms

    which contains five consecutive terms that are even and not all identical

    Answer:

    the answer is 2+3
