“Last DIGIT Series”

This collection of images focusses on the odd and even LAST DIGITS of decimal numbers. The importance of Last Digits is:-

  • the distinction between odd [1 3 5 7 9] and even [0 2 4 6 8];
  • the identification as a possible Prime Number [only sum not product]: 1 3 7 9.

In search of a solution to the Prime Number problem, we keep 1 3 7 9 under scrutiny as Last Digits.

In the Pyramid shape, columns alternate between odd and even.

Rows offer predictable growing intervals in series of five digits.

Pyramids provide for VERTICAL as well as HORIZONTAL Series of Decimal Numbers
