Answer 2

Step-by-step explanation:

Heya !!

Given :-

• The sum of three consecutive odd natural numbers is 69

To Find :-

• find the numbers and identify the prime number out of these numbers

supposed the numbers is x

then ,

• x +2 and x + 4

According to the question

x + x + 2 + x + 4 = 69

3x + 6 = 69

3x = 69 - 6

3x = 63

x = 63/3

x = 21

then,

First number. x = 21

second number x + 2 = 21 + 2 = 23

third number x + 4 = 21 + 4 = 25

Hence Prime number is 23.
