Worked practice questions
As per your syllabus, the GENERAL form of a GP with first term a and common ratio r is which expression?
- a, a + r, a + 2r, a + 3r, ...
- a, a², a³, a⁴, ...
- a, ar, ar², ar³, ..., arⁿ⁻¹, ...
- a, a × r, a × r², a × r³ + r
Show answer and solution
Correct answer: C. a, ar, ar², ar³, ..., arⁿ⁻¹, ...
As per your syllabus, GP form: a, ar, ar², ar³,..., arⁿ⁻¹.
The other options describe APs or are wrong.
As per your syllabus, the nth TERM of a GP with first term a and common ratio r is given by which formula?
- tₙ = a + (n − 1)r
- tₙ = a × n × r
- tₙ = a + rⁿ
- tₙ = a × rⁿ⁻¹
Show answer and solution
Correct answer: D. tₙ = a × rⁿ⁻¹
As per your syllabus, nth term of GP = a × rⁿ⁻¹.
The other formulas misstate.
