So, Let's call N two (for an example). Since two is an even number, but we could really put any even number.
3(2) -1 = 5 (ODD)
(3)2-2 = 4 (EVEN)
3(2) + 2(2) = 10 (EVEN)
3(2) + 2 = 8 (EVEN)
The answer is bolded
Answer:
Option A is correct!
Step-by-step explanation:
Since 3n is even number and we know that previous and next number of an even is always an odd number
here the first option is 3n-1 which means one less than 3n that means the number previous to 3n so it is odd .
3n-2 means 2 number lesser than 3n which is again even number.
same argument will be given for 3n+2
2n means even number because n is multiple of 2
sum of two even is again even therefore 32n is again even.
