Arithmetic Progressions - Quick Notes & Formula Sheet Class 10 CBSE Mathematics · Chapter 5 · Complete Revision Guide (2026-27) 1. What is an Arithmetic Progression (AP)? A list of numbers in which each term (after the first) is obtained by adding a fixed number, called the common difference (d) , to the previous term. d = a 2 - a 1 = a 3 - a 2 = ... (constant throughout) Trap: d can be negative or a fraction Students often assume an AP must increase. A decreasing sequence (d negative) or one with fractional/decimal common difference is still a valid AP - always compute d by subtraction, don't just "look" at the sequence. 2. nth Term Formula (Highest Weightage) a n = a + (n-1)d Where a is the first term, d is the common difference, and n is the position of the term you want. Trap: Off-by-one error in (n-1) The most common ...

Q. A heavy iron bar of weight W has one end resting on the ground and the other on the shoulder of a person. The bar makes an angle θ with the horizontal. The weight experienced by the person is: W W sinθ W/2 W cosθ Check Answer Show Explanation Correct Answer: W/2 Taking moments about the end touching the ground, F × L cosθ = W × (L/2) cosθ ⇒ F = W/2 Hence the force experienced by the person is W/2 , independent of θ.

Arithmetic Progressions - Quick Notes & Formula Sheet Class 10 CBSE Mathematics · Chapter 5 · Complete Revision Guide (2026-27) Syllabus Note for 2026-27 This chapter's core focus is mastery of the nth term and sum of n terms formulas - CBSE consistently emphasizes these two skills above everything else here. Real-life word problems (salary increments, savings patterns, stadium seating, etc.) using both formulas remain part of the current NCERT Reprint 2026-27 scope, so don't skip practicing them even if you've seen older material suggesting otherwise. 1. What is an Arithmetic Progression? An Arithmetic Progression (AP) is a sequence of numbers in which the difference between any two consecutive terms is constant. This constant is called the common difference (d) . General AP: a, a+d, a+2d, a+3d, ... Here a is the first term. To check if a sequence is an...
