Let us say two odd numbers are p and q. And we know that sum of two odd numbers is always even. But the average of two odd numbers is not always even. Average of p and q = (p+q)/2 = even number/2 = odd or even. Two examples will make it clear. e.g. Average of 5 and 1 = (5+1)/2 = 6/2 = 3(odd number) Average of 3 and 5 = (3+5)/2 = 8/2 = 4(even number) So, average of two odd numbers can be even or odd.
1610025 = 3*5*5*21467 has 12 factors and 12 is NOT an odd number.

Consecutive numbers will always total an odd number. Consecutive odd numbers or consecutive primes would be 5 and 7.
This is not always true. If the sum of two numbers is even, then those two numbers are either both even or both odd. For example: 2 + 2 = 4 (even + even = even) 5 + 7 = 12 (odd + odd = even) 3 + 2 = 5 (odd + even = odd)
1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23 are the first 12 odd numbers.

No (Assuming you mean if they are added together).The sum of an odd number (e.g. 5) of odd numbers will always be odd!
