1. The user's message "For the first A.p" is ambiguous and does not specify a clear math problem to solve. 2. "A.p" often stands for Arithmetic Progression (Arithmetic Sequence), a sequence of numbers where the difference between consecutive terms is constant. 3. If you want to find the first term of an A.P., denote it as $a_1$. 4. The nth term of an arithmetic progression is given by the formula $$a_n = a_1 + (n-1)d$$ where $d$ is the common difference. 5. Without additional information such as the common difference, a term value, or the number of terms, we cannot find the exact first term. 6. Please provide more details or a specific problem involving the arithmetic progression.
