Answer:
C: 2m + 1
Step-by-step explanation:
If m + 1 is even, then m is odd.
A: m - 1 is even
B: 2m - 2 is even
C: 2m + 1 is odd
D: 2m + 2 is even
Answer:
Option C.
Step-by-step explanation:
Even number : A number is called even if it is divisible by 2, i.e., 2, 4, 6,...
Odd number : A number is called odd if it is not divisible by 2, i.e., 1,3,5,...
It is given that m + 1 is an an even integer.
Since alternate numbers are even, therefore m must be an odd number.
If m is odd, then m-1 is even.
2m is divisible by 2, so it is always an even number. So,
2m - 2 is even.
2m+1 is odd.
2m+2 is even.
Since 2m+1 is an odd number, therefore the correct option is C.
