Q65.If the sum and product of the first three terms in an A. P. are 33 and 1155, respectively, then a value of its 11th term is: (1) −25 (2) −35 (3) 25 (4) −36
What This Question Tests
The problem provides the sum and product of the first three terms of an AP. By representing the terms as `a-d, a, a+d`, one can find the common difference `d` and the first term `a`, and then calculate the 11th term.
Concepts Tested
Formulas Used
a-d, a, a+d
