Question

The sum of 7 consicutive natural numbers is 70. What are the numbers

Answer 1

Answer:

the seven consecutive natural numbers are 7,8,9,10,11,12,13

Step-by-step explanation:

As the numbers are consecutive, then 2nd, 3rd, 4th, 5th, 6th and 7th numbers will be (x + 1), (x + 2), (x + 3), (x + 4), (x + 5) and (x + 6) respectively.

(x) + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) = 70

⇒ 7x + 21 = 70

⇒ 7x = 70 - 21

⇒ 7x = 49

⇒ x = 49/7

⇒ x = 7

The first number is 7.

2nd number = 7 + 1 = 8

3rd number = 7 + 2 = 9

4th number = 7 + 3 = 10

5th number = 7 + 4 = 11

6th number = 7 + 5 = 12

7th number = 7 + 6 = 13
