Which among the following is/are characteristics(s) of reasoning in mathematics ?
(A) Looking for patterns
(B) Solving a problem using a formula
(C) Making and testing conjectures
Choose the correct option :

Correct option is B

All three of the listed options are characteristics of reasoning in mathematics.
Looking for patterns is a key aspect of mathematical discovery. By identifying patterns in data or relationships between concepts, mathematicians are able to make conjectures and develop new theories.
Solving a problem using a formula is a common task in mathematics. Formulas provide a concise and efficient way to represent mathematical relationships, and they can be used to solve a wide variety of problems.
Making and testing conjectures is a fundamental part of mathematical reasoning. Conjectures are tentative statements that are based on observation or intuition, and testing conjectures involves trying to prove or disprove them using rigorous mathematical methods.
