Are there any numbers which cannot be made as the result of adding consecutive numbers however many you use?

Numbers which are a power of 2 (1,2,4,8,16,32,64,...) cannot be made by summing consecutive numbers.


Can you name 2 consecutive prime numbers whose product is 899?

The product between the consecutive prime numbers of 31 and 29 yield a result of 899.


Why is it when you add two consecutive numbers the result is always even?

4+5=9


The product of two consecutive integers is 6?

This is quickly solved by trial-and-error. Try multiplying two consecutive integers. If the result it too high, try again with lower numbers. If the result is too low, try again with higher numbers.


Why when every three consecutive number are being multiplied it gives you an answer which is an even number?

Any two consecutive numbers must comprise one odd and one even number, so their product must be even. Any three consecutive numbers must include two consecutive numbers so the result still applies.


What are two consecutive integers whose sum equals -30.03?

Integers are whole numbers therefore it follows that two consecutive integers can't result into a decimal number


Is the number of two prime numbers prime?

Combining prime numbers other than 2, whether through addition or multiplication, will result in a composite number.


What is the Product of two consecutive prime numbers?

There is only one pair of consecutive prime numbers, and the prime numbers are two and three, because any pair of consecutive numbers has one odd and one even number, and two is the only even prime number, because all other even numbers can be divided by two, and the only pairs of consecutive numbers are one and two and three, but one is not prime because it only has one factor, thus making the only consecutive pair of primes two and three. But the problem asks for the product of the two numbers, not the numbers themselves, so just multiply two and three together to get a final result of six.


What is a triangle made of metal and pot?

A metal triangle is a percussion instrument consisting of a metal rod bent into a triangle shape, and a pot is a container typically made of ceramic or metal used for cooking or storing food. Combining the two would result in a metal triangle suspended above a pot, with the potential for creating musical sounds by striking the triangle.


Will two consecutive numbers ever have a greatest common factor greater than 1?

No. The GCF of any two numbers is also a factor of their difference. The difference between consecutive numbers is 1 so their GCF must also be a factor of 1. The only factor of 1 is 1 - and hence the result.


The sum of two consecutive integers is 228 what are the numbers?

This would be impossible as, seeing as one of the integers would be odd, the result would be an odd number.


2 consecutive numbers for 257?

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.
