Question

And the last question is: The sum of two consecutive integers is at least 14. What is the least possible pair of integers? A) 4 and 5 B) g and 7 C) 7 and 8 D) 8 and 9

Answer 1

7 and 8

Explanation:

Given The sum of two consecutive integers is at least 14.

Let the two consecutive digits be x and x+1

The condition that should be satisfied by these numbers is that their sum must be atleast 14.

`x+(x+1)\geq 14`

`2x+1\geq 14`

`2x\geq 13`

`x\geq (13)/(2)`

`x\geq 6.5`

Since x is an integer x=7 and the other digit is 8.
