odd multiples of 7 are odd numbers.. like 7*1, 7*3,7*5..
The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.
Starting with 7, every other multiple is odd.
No odd numbers are multiples of 4.
All integers have an infinite amount of multiples.

The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.

Odd multiples of 21.
No - alternate multiples of 3 are odd, and alternate multiples are even.
For 2 to be a factor, the number has to be even. If you multiply two odd numbers together, you get an odd number. 7 is odd, so if I multiply it by any odd number, I will get a number that doesn't have 2 as a factor (e.g. 7x5=35 which doesn't have 2 as a factor). Thus, the answer to the question is "no," not all multiples of 7 have 2 as a factor.
No odd numbers are multiples of 4.
All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.
Because not all odd numbers are multiples of 3 - I have shown you below that this is the case and you can see some multiples of 3 are even and some are odd and you can also see that there are even and odd numbers BETWEEN the multiples of 3. 1 (odd) 2 (even) 1*3 =3 (odd) 4 (even) 5 (odd) 2*3 = 6 (even) 7 (odd) 8 (even) 3*3 = 9 (odd) 10 (even) 11 (odd) 4*3 = 12 (even)

The factors of 35 are 1, 5, 7, 35. All of them are odd. 7 and 35 are multiples of 7. 5 has a digit sum equal to 5. No number satisfies all of the conditions.
50 is an even number so ALL its multiples are even...
