Worked practice questions
As per your syllabus, the nth term of an AP with first term a and common difference d is given by which formula?
- tₙ = a + (n − 1)d
- tₙ = a × n + d
- tₙ = a × dⁿ⁻¹
- tₙ = a + n × d
Show answer and solution
Correct answer: A. tₙ = a + (n − 1)d
As per your syllabus, nth term of AP = a + (n − 1)d.
The other formulas misstate or describe GP.
As per your syllabus, what is the 10th term of the AP 3, 8, 13, 18,...?
- 53
- 58
- 48 (using tₙ = a + (n−1)d = 3 + 9 × 5)
- 45
Show answer and solution
Correct answer: C. 48 (using tₙ = a + (n−1)d = 3 + 9 × 5)
As per your syllabus, a = 3, d = 5, t₁₀ = 3 + (10 − 1) × 5 = 3 + 45 = 48.
