Chapter 5: Arithmetic Progressions

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

1. 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.
2. 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.
3. 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
