A coefficient in literal form in an algebraic term is called a literal coefficient. In mathematics, a coefficient is basically a multiplicative factor in a term but in algebra, a literal coefficient is a multiplying factor which contains one or product of more literal numbers in an algebraic term. Examples $(1) \,\,\,\,\,$ $7a$
These properties apply to all regular polygons, whether convex or star. A regular n-sided polygon has rotational symmetry of order n. All vertices of a regular polygon lie on a common circle (the circumscribed circle), i.e., they are concyclic points. That is, a regular polygon is a cyclic polygon.
Proof by mathematical induction. ( 1 i) P(1) is true, i.e., P(n) is true for n = 1. ( 2 ii) P(n+1) is true whenever P(n) is true, i.e., P(n) is true implies that P(n+1) is true. 3  Then P(n) is true for all natural numbers n.
