UP Board Class 11 Maths – Sequences and Series

The chapter Sequences and Series in UP Board Class 11 Maths introduces students to the systematic arrangement of numbers and the patterns that connect them. A sequence is an ordered list of numbers, while a series is the sum of the terms of a sequence. This chapter helps students identify patterns, understand term-to-term relationships, and compute sums efficiently.

1 / 0 100%


Students learn about Arithmetic Progression (AP), Geometric Progression (GP), and various formulas related to their nth term, common difference/ratio, and sum of terms. The chapter also covers special series like arithmetic-mean and geometric-mean, which play an important role in higher mathematics.

The concepts in this chapter build a solid base for calculus, algebra, and real-life mathematical applications such as growth patterns, interest calculations, and data analysis. With examples, formulas, and practice exercises, the chapter strengthens analytical thinking and prepares students for the UP Board exam as well as competitive exams like JEE and NDA.
