x_{1}, x_{2}, \ldots ., x_{n}

and

\frac{1}{h_{1}}, \frac{1}{h^{2}}, \ldots . \frac{1}{h_{n}}

are two A.P's such that

x_{3}=h_{2}=8

and

x_{8}=h_{7}=20

, then

x_{5} . h_{10}

equals.

View answer and explanation

Correct option: A

2560

Option A (2560) is correct because it is the product of x_5 and h_10, calculated using the properties of arithmetic progressions.
