The sum of the first 50 multiples of 5 is 6,375. Here's how to calculate it: - Identify the pattern: The first 50 multiples of 5 are: 5, 10, 15, 20... 250- Arithmetic Series: This is an arithmetic series where the first term (a) is 5, the common difference (d) is 5, and the number of terms (n) is 50.- Formula: The sum (S) of an arithmetic series is S = (n/2) * [2a + (n-1)d]- Calculation: S = (50/2) * [2(5) + (50-1)5] = 25 * [10 + 245] = 25 * 255 = 6,375 Therefore, the sum of the first 50 multiples of 5 is 6,375HOPE YOU GIVE US A PERFECT STAR
