About this Arithmetic Progression chapter test
This test is for Chapter 3 of the Class 10 Algebra syllabus. Its 10 questions move from basics to board-style problems: finding the common difference, deciding which sequence is an A.P., and finding t₅ from a and d. You then work with the nth term formula tₙ = a + (n-1)d to find which term equals −20 and to count two-digit numbers divisible by 3. The last part is about sums: the first 20 natural numbers, S₁₅ for a given A.P., finding the 10th term when Sₙ = n² + 2n, and solving for k when three expressions are consecutive terms.

How to get the most from it
Take the test after you finish all practice sets of the A.P. chapter. Write the formula you are using before calculating; most mistakes in this chapter come from mixing up tₙ and Sₙ. Review the worked explanation for each question after submitting. If you get fewer than 6 right, revise the derivation of Sₙ = n/2[2a + (n-1)d] and try again later.
