- Introduction to Arithmetic Progressions
- nth Term of an AP
- Sum of First n Terms of an AP

- Introduction to Arithmetic Progressions: This section introduces the concept of arithmetic progressions (AP) and their properties. It discusses the common difference, first term, and nth term of an AP.
- nth Term of an AP: This section explains how to find the nth term of an AP using the formula an = a + (n-1)d, where a is the first term, d is the common difference, and n is the term number.
- Sum of First n Terms of an AP: This section explains how to find the sum of the first n terms of an AP using the formula Sn = (n/2)(2a + (n-1)d), where a is the first term, d is the common difference, and n is the number of terms.

Overall, Chapter 5 of NCERT Maths textbook for class 10 provides an introduction to arithmetic progressions and their properties. It lays the foundation for further study of sequences and series in later chapters
