What do you mean by numbers?

A number is a mathematical object used to count, measure, and label. Numbers can be represented in language with number words. More universally, individual numbers can be represented by symbols, called numerals; for example, “5” is a numeral that represents the number five.

How to find the formula for a stellar number?

We can then generalise to find stellar number formulae for different numbers of vertices. For example the 5-stellar numbers pictured above have the formula 5n 2 – 5n + 1. In fact the p-stellar numbers will have the formula pn 2 – pn + 1.

What kind of scale is the stellar magnitude scale?

The Stellar Magnitude Scale One of the most common terms that you will encounter in astronomy is stellar magnitude. It is the scale astronomers use to measure the brightness of all astronomical objects from stars and planets to distant galaxies and quasars.

How are the triangular numbers used in stellar numbers?

A more interesting method makes use of the triangular numbers. We can first note a recurrence relationship in the stellar numbers – each subsequent pattern contains all the previous patterns inside. In fact we can state the relationship as: The outside star edge of S 2 can be thought of as 6 copies of the 2nd triangular number
