The two numbers that have a sum of 70 are 35 and 35. This is because when you add 35 and 35 together, you get 70. Another way to think about it is that if you have two numbers x and y that add up to 70, then x + y = 70. By substituting 35 for both x and y, you get 35 + 35 = 70.
29 & 41
There are five ways to get a sum of 70 with two prime numbers: 3 + 67 = 70 11 + 59 = 70 17 + 53 = 70 23 + 47 = 70 29 + 41 = 70.
the 2 numbers are 51 and 19
70 + 19 = 89 or: the sum of 70 and 19 is 89
If the sum of the original seven numbers is 2814, and they're all increased by 70, the new total will be 2814+490=3304

70 + 19 = 89 or: the sum of 70 and 19 is 89
If the sum of the original seven numbers is 2814, and they're all increased by 70, the new total will be 2814+490=3304
Since there are 2 numbers in the group, the group average is 1/2 of their sum.
There cannot be any such set of numbers. The sum of any five odd numbers must be odd and so cannot be 70.

The sum of the first 70 consecutive odd numbers is 4,900.
The numbers are 69, 70, and 71.
