No because it is 30 which can be divided by 2
Lets find out.2 + 3 = 5 (Odd)4 + 7 = 11 (Odd)12 + 13 = 25 (Odd)So it appears that the sum of an even and odd number is an odd number.
To make odd numbers total an odd number, you have to have an odd number of them. 7 + 13 + 43 = 63
All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.
The smallest odd 7-digit number is 1,000,001 .If you also want the ones digit to be the sum of the thousands and ten-thousands digits,then the smallest odd 7-digit number that satisfies that additional requirement is 1,001,001,but it's no longer the smallest odd 7-digit number.
1000001 is the smallest 7 digit odd number...
The sum of an odd number and an even number is an odd number.
No two odd numbers can sum to 7.
Lets find out.2 + 3 = 5 (Odd)4 + 7 = 11 (Odd)12 + 13 = 25 (Odd)So it appears that the sum of an even and odd number is an odd number.
To make odd numbers total an odd number, you have to have an odd number of them. 7 + 13 + 43 = 63

1000001 is the smallest 7 digit odd number...
As the number is odd it must end in an odd digit; the odd digits are 1, 3, 5, 7, 9 and the smallest is 1 which is the sum of 1 and 0. Thus the smallest 7-digit number which meets your criteria is 1,001,001
7 & 29, 13 & 23, 17 & 19...
How many odd numbers are there from 16 to 30? Seven {7} odd numbers
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.,
the sum of 7 and 23 is 30..
