24 and 25 - add 1 to 49, gives 50. Half it, gives you 25. 2 x 25 = 50, take 1 away from one of the 25's = 24 and 25 = 49.
100 + 49 + 1
2 and 1 .their sum is 3 .difference is 1
The first seven odd numbers are 1, 3, 5, 7, 9, 11, and 13. To find their sum, you can add them together: 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49. Therefore, the sum of the first seven odd numbers is 49.

The numbers are 15 and 1
1 + 3 + 5 + ... + 49 = ((49 + 1)/2)2 = 625
81 + 1 + 1 + 1
100 + 49 + 1
2 and 1 .their sum is 3 .difference is 1
1 and 0 are the two whole numbers with their sum same as their difference
The first seven odd numbers are 1, 3, 5, 7, 9, 11, and 13. To find their sum, you can add them together: 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49. Therefore, the sum of the first seven odd numbers is 49.

The numbers are 15 and 1
24 and 25. To solve almost any question like this mathematically by using simple algebra. For example: Let one of the numbers be x and the other be x + 1. Then x + x + 1 = 49 so 2x + 1 = 49 so 2x = 48 so x = 24 and the other is x + 1 = 25.
15 + 1 = 16 sum 15 - 1 = 14 difference
