Question

add two consicutive natural numbers and find the number, one less than this​

Answer 1

Step-by-step explanation:

Let the two consecutive natural numbers be a & (a+1). Now the number one less than this will be (2a + 1) - 1 = 2a + 1 - 1 = 2a. i.e. twice the first number. Therefore, the number one less than the sum of two consecutive natural numbers will be twice the sum of the smaller number.

Answer 2

Answer:

Twice

Step-by-step explanation:

Let the two consecutive natural numbers be = a

                                                                          = (a+1)

The sum of the numbers will be a + a + 1 = 2a + 1

Now,    

          The number one less than this will be (2a + 1) - 1 = 2a + 1 - 1

                                                                                           = 2a.

Therefore, the number one less than the sum of two consecutive natural numbers will be twice the sum of the smaller number.
