Answer 1

Answer:

1.) Triangular numbers:- A triangular number or triangle number counts objects arranged in an equilateral triangle. The nth triangular number is the number of dots in the triangular arrangement with n dots on a side, and is equal to the sum of the n natural numbers from 1 to n.

2.) Prime factorization :- In number theory, integer factorization is the decomposition of a composite number into a product of smaller integers. If these factors are further restricted to prime numbers, the process is called prime factorization.

3.) Rational numbers :- In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number

4.) Estimation:- Estimation (or estimating) is the process of finding an estimate, or approximation, which even with little data it cannot find the population parameter, uncertain, or unstable. The value is nonetheless unusable because it is derived from the Worst information available.
