### Instruction: help me answer this question Find four numbers forming a geometric progression in which the third term is greater than the first term by 9, and the second term is greater than the 4th by 18., think step by step
### Assistant: The given conditions lead us to a system of equations, which we solve to find the first term (a) and the common ratio (r). Substituting these values, we find the first four terms of the G.P. , The answer is The first four numbers of the G.P. are 3, 3(-2), 3(-2)^2, and 3(-2)^3 i.e., 3, -6, 12, and -24.
