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 numbers are 15 and 1
55
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.
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 numbers are 15 and 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.
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
