Here are the solutions for questions 6 and 7.

Question 6:
Given that (x+2)(x+2), (4x+3)(4x+3) and (7x+24)(7x+24) are consecutive terms of a Geometric Progression (G.P.).

For a Geometric Progression, the square of the middle term is equal to the product of the first and third terms. Let the terms be a1=x+2a_1 = x+2, a2=4x+3a_2 = 4x+3, and a3=7x+24a_3 = 7x+24.
So, a22=a1a3a_2^2 = a_1 a_3.

Step 1: Set up the equation using the G.P. property.
