The sum of five consecutive numbers is 20.what is the sum of first three consecutive numbers |
|
Answer» Let the smaller number of five consecutive natural number be xThus other four consecutive natural numbers are x + 1, x + 2, x + 3 and x + 4As per statement the sum of five consecutive natural numbers is 20. To FIND the largest numbers.x + x + 1 + x + 2 + x + 3 + x + 4 = 205x + 10 = 205x = 20 - 105x = 10x = 10 / 5x = 2Thus smaller consecutive natural number is 2, The other four consecutive natural numbers arex+ 1 = 2 + 1= 3;x + 2= 2 + 2= 4x + 3 = 2 + 3= 5x + 4 = 2 + 4 = 6Thus five consecutive natural numbers are 2, 3, 4, 5 and 6Answer largest of five consecutive natural number is 6Let us CHECK the correctness of answer by taking their sum, which should be 202 + 3 + 4 + 5 + 6 =2020 = 20 |
