The correct Answer is:
To solve the problem, we need to find the third term of a geometric progression (G.P.) given that the product of five consecutive terms is 1024. Let's denote the first term of the G.P. as \( a \) and the common ratio as \( r \). ### Step-by-Step Solution: 1. **Identify the Terms of the G.P.**: The five consecutive terms of the G.P. can be expressed as: - First term: \( a \) - Second term: \( ar \) - Third term: \( ar^2 \) - Fourth term: \( ar^3 \) - Fifth term: \( ar^4 \) 2. **Set Up the Product Equation**: The product of these five terms is given by: \[ P = a \cdot ar \cdot ar^2 \cdot ar^3 \cdot ar^4 \] This simplifies to: \[ P = a^5 \cdot r^{0+1+2+3+4} = a^5 \cdot r^{10} \] We know that this product equals 1024: \[ a^5 \cdot r^{10} = 1024 \] 3. **Express 1024 as a Power of 2**: We can express 1024 as a power of 2: \[ 1024 = 2^{10} \] Therefore, we have: \[ a^5 \cdot r^{10} = 2^{10} \] 4. **Equate the Powers**: We can rewrite \( a^5 \cdot r^{10} \) in a different form: \[ (ar^2)^5 = a^5 \cdot r^{10} \] This means: \[ ar^2 = 2^2 = 4 \] Thus, the third term \( T_3 \) of the G.P. is: \[ T_3 = ar^2 = 4 \] 5. **Conclusion**: The third term of the set is: \[ \boxed{4} \]
