Step-by-step explanation:

first put some odd value on the place of k such as we put 1 in the place of k then the ans. will be 2+7 --9 okk thats mean if we put any integer in the place of k then the ans.will be odd

Answer 2

We know that ,

The integer which are all divisible by 2 are an even numbers.

2k is divisible by 2.

while , 7 can be written as (2×3) + 1

(2×3) is divisible by 2.

and we know 1 is odd number.

so from that we conclude,

2k + (2×3) + 1

2(k+3) + 1

even + 1 is odd integer.

so 2k+7 is odd integer.
