Question

first and second term and third term of an ap is 36 the 12th term of an ap is square of its second term find the AP​

Answer 1

Answer:

Let the arithmetic progression be given by: a, a+d, a+2d, a+3d, …., where a is the 1st term and d is the common difference. The 2nd term of the AP is a+d, the 3rd term is a+2d, and the 6th is a+5d. (a+2d) / (a+d) = (a - 4a) / (a - 2a) = (-3a) / (-a) = 3.
