128.5 if you're talking about consecutive numbers.
257/2 = 128.5 so 128 and 129
There are no two consecutive numbers that add or multiply to 102.
There are no four consecutive whole numbers that add up to 35. The sum of two consecutive [whole] numbers is an even number plus an odd number which is an odd number. The sum of two consecutive numbers and the two next consecutive numbers is the sum of two odd numbers which is even, but 35 is odd, so no four consecutive whole numbers cannot add up to 35.
Consecutive whole numbers will have an odd sum. Consecutive odd numbers, or consecutive prime numbers, will be 29 and 31.
I am not sure if any two consecutive numbers can add up to an even number.
20 + 19 = 39The two consecutive numbers that add up to 39 are 19 and 20.
Two consecutive numbers (pressumably integers) will always add up to an odd number, so this has no solution. If you mean "two consecutive even numbers" or "two consecutive odd numbers", you should quickly be able to find a solution by trial-and-error.
Consecutive numbers will always total an odd number. Consecutive odd numbers or consecutive primes would be 5 and 7.
The numbers are 13 and 14.
If you mean that the sum of two consecutive numbers should be 257, here are two ways to solve it: 1) Trial and error. Just try out different numbers; if the sum is too large, try again with smaller numbers; if the sum is too small, try again with larger numbers. 2) With algebra, you can get the result faster. Call the first number "x", then the second number is "x + 1". Thus, you get the equation: x + (x + 1) = 257 Solve this for "x", and you get the first of the two consecutive numbers.
