A Diginacci sequence is created as follows. The 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
+
1 - List the first 26 terms of the Diginacci sequence above,
2 - Find, with explanation, two starting terms for a Diginncei sequence
so that its 2021st term is 11.
3 - Find, with explanation, a Diginacci sequence that has no term equal
to 11
4- Find with explanation, a sequence with two different starting terms
which contains five consecutive terms that are even and not all iden-
tical
