Question

O. The sum of two consecutive natural numbers is 69. Find the numbers.
Solution:​

Answer 1

Answer :-

Given :-

• Sum of two consecutive natural numbers = 69

To Find :-

• Numbers

Solution :-

Let the number be x

Consecutive number = x + 1

According to the question :-

→ x + x + 1 = 69

→ 2x + 1 = 69

→ 2x = 69 - 1

→ 2x = 68

→ x = 68 / 2

→ x = 34

Numbers = 34 and 35

Answer 2

Given :

• The sum of two consecutive natural numbers is 69.

To Find :

• The Numbers

Solution :

✰ In this question, it is given that The sum of two consecutive natural numbers is 69 and we know that natural numbers starts from 1 and they are counting numbers. So, let's assume the first natural number be p and second natural number be p + 1 .

⠀⠀⠀

⠀⠀⟼⠀Sum of Natural Numbers = 69

⠀⠀⟼⠀p + p + 1 = 69

⠀⠀⟼⠀2p + 1 = 69

⠀⠀⟼⠀2p = 69 - 1

⠀⠀⟼⠀2p = 68

⠀⠀⟼⠀p = 68/2

⠀⠀⟼⠀p = 38

⠀

Thus, Two Consecutive Natural Numbers whose sum is 69 are 34 and 35.
