Question

Find 3 Consecutive integers sum of first and second is 15 more than third​

Answer 1

Answer:

The three consecutive natural numbers are 16, 17 and 18.

Step-by-step explanation:

• Let the first consecutive number = x,

•              second consecutive number = x + 1

•              third consecutive number = x + 2

• From the given condition,

• x + ( x + 1 ) =15 + ( x + 2 )

• Solving this,
• ⇒( 2x + 1 ) = ( 17 + x )  
• ⇒( 2x - x ) = ( 17 - 1 )  
• ⇒ x=16
• ∴The first natural number = x = 16  
• Second natural number = x+1 = 16+1 = 17  
• Third natural number = x +2 = 16 + 2=18
• Hence, the required three consecutive natural numbers are 16, 17 and 18.
