Activity 3: intro to sum of terms of an A.S math
Answer (1)
Answer:Introduction to the Sum of Terms of an Arithmetic Sequence (A.S.)An arithmetic sequence is a list of numbers where the difference between consecutive terms is constant. This difference is called the common difference (d).To find the sum of the first n terms of an arithmetic sequence, we use the formula:S_n = \frac{n}{2} (a_1 + a_n)orS_n = \frac{n}{2} [2a + (n - 1)d]Where: is the sum of the first n terms or is the first term is the nth term is the common difference is the number of terms
