MCQ
For some integer q, every odd integer is of the form:
  • A
    q
  • B
    q + 1
  • C
    2q
  • 2q + 1

Answer

Correct option: D.
2q + 1
We know that, all numbers that are not the multiple of 2 are odd numbers.
Odd integers are ..., -3, -1, 1, 3, 5,...
So, odd numbers can be written as 2m + 1, where m is an integer.
m can be ..., -2, -1, 0, 1, 2,...
$\therefore$ 2m + 1 can be ..., -3, -1, 1, 3,...
Hence, the correct answer is option D.
