3 + 8 is 11.
11 is an odd number.
No -an odd and an odd equals even ( 5+3=8) -an even and an odd equals odd (2+3=5) -an even and an even equals even (4+6=10)
Since 270 is an even number, then three consecutive odd numbers cannot add to 270. ,because Odd + odd = even (2 numbers_ Even + odd = odd ( plus a third number) odd + odd = even (plus a fourth number) even + odd = odd (plus a fifth number) Notice from the table that the third odd number gives an odd answer; not an even answer. e.g. three odd numbers 3,5, & 7. 3 + 5 = 8 (even) 8 + 7 = 15 ( odd) et. seq.,
Alternating. 1 2 3 4 5 6 7 8 9 in row 3, (7,8,9) the 8 is even and the 7 and 9 are odd. thus odd,even,odd. in column 3, (3,6,9) the 6 is even and the 3 and 9 are odd, thus odd,even,odd. as the row/column selector (3) is odd the first digit in that row/column of a 3X3 grid will be odd as will the first. the numbers then alternate even odd even.
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 answer would be equal. For example 3+5=8 which is even.
7 and 3 are the odd ones. 8 is an even integer.
opposite - answer will always be odd (when adding odd + even) odd + even 5 + 4 = 9 odd even + even 2 + 6 = 8 even odd + odd 3 + 1 = 4 even
odd ends 1 3 5 7 9 even 0 2 4 6 8
even ends in 8 which is an even number 0 2 4 6 8 odd numbers are 1 3 5 7 9
It may or it may not. Parity (whether the number is odd or even) has nothing to do with a sum of two odds being positive or negative. -5 + 3 = -2 is negative, while 5 + 3 = 8 is positive.
odd even ends 0 2 4 6 8 odd ends 1 3 5 7 9
8 is an even number, like 2 4 6 & 8, examples of odd numbers would be 1 3 5 & 7.
