Let

a_1, a_2, \ldots, a_{10}

be in AP and

h_1, h_2, \ldots, h_{10}

be in HP. If

a_1=h_1=2

and

a_{10}=h_{10}=3

, then

a_4 h_7

View answer and explanation

Correct option: D

Option D (6) is correct because by using the properties of AP and HP, we can find the values of a_4 and h_7 and then calculate their product.
