AI Generated Solution

To solve the problem, we need to find three numbers in a Geometric Progression (G.P.) whose sum is 14. Additionally, if the first two terms are increased by 1 and the third term is decreased by 1, the resulting numbers should form an Arithmetic Progression (A.P.). ### Step-by-Step Solution: 1. **Assume the Terms of G.P.**: Let the three numbers in G.P. be \( a \), \( ar \), and \( ar^2 \). - Here, \( a \) is the first term and \( r \) is the common ratio. ...
