How do you use inductive reasoning to prove the product of an odd integer and an even integer will always be even?

The product of an odd and even number will always have 2 as a factor. Therefore, it will always be even.

How do you prove 2n is the sum of two odd consecutive integers?

2n can be split into 2 n's so: n+n then add one to one of the n's and subtract one from one of the n's n+1+n-1 ^two consecutive odd integers^

Suppose x and y are odd prove xy is odd?

Write x and y in terms of integers, which we call a and b. For some integer, x = 2a + 1 y = 2b + 1 Multiplying them, you get: xy = (2a+1)(2b+1) = 4ab + 2a + 2b + 1 Since the first terms are even, adding one makes the final result odd.

If you add 3 to an even number the sum would be odd or even?

Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd

Is 49 even or odd?

49 is an odd number numbers ending in 1,3,5,7,9 are odd.

What is the formula to find sum of n odd numbers?

The set of odd numbers is an arithmetic sequence. Let say that the sequence has n odd numbers where the first term is a1 and the last one is n. The formula to find the sum on nth terms for an arithmetic sequence is: Sn = (n/2)(a1 + an) or Sn = (n/2)[2a1 + (n - 1)d] where d is the common difference that for odd numbers is 2. Sn = (n/2)(2a1 + 2n - 2)

How can you determine whether a function is even odd or neither?

Looking at the graph of the function can give you a good idea. However, to actually prove that it is even or odd may be more complicated. Using the definition of "even" and "odd", for an even function, you have to prove that f(x) = f(-x) for all values of "x"; and for an odd function, you have to prove that f(x) = -f(-x) for all values of "x".

How do you use inductive reasoning to prove the product of an odd integer and an even integer will always be even?

The product of an odd and even number will always have 2 as a factor. Therefore, it will always be even.

How to prove that A being any number A multiplied by A plus 1 is always divisible by 2?

A will always be an odd number.

How do you find the sum of the first thirty odd integers?

The arithmetic sequence of odd integers is 1, 3, 5, 7, 9, ... where the common difference is 2. The sum of the first thirty odd integers can be found by using the sum formula such as: Sn = n/2[2a1 + (n - 1)d], where a1 = 1, n = 30, and d = 2. So, S30 = (30/2)[(2)(1) + (30 - 1)(2)] = (15)[2 + (29)(2)] = (15)(60) = 900

What round does a rfi 7.62mm 2a1 take?

The 7. 62mm 2A/2A1 is a 7. 62mm NATO, also called 7. 62Ã?51 caliber. Although the 7. 62mm NATO and commercial . 308 Winchester ammunition are physically interchangeable, these weapons were not designed for use with commercial . 308 ammo.

Odd number of digits in a palindrome to be divisible by 11?

No, not necessarily. 121 is a palindrome number with 3 digits (odd) and is divisible by 11. So this satisfies the premise, but 101, 111, 131, etc are not divisible by 11.An example which satisfies the premise does not prove it true, but one which contradicts the premise is enough to prove it false.

If n is an odd integer prove 8 divides n of n-1?

Since numbers are relatively prime if their greatest common factor is 1 how do you prove that successive odd numbers are prime?

Find their GCF.

How do you prove that if you multiply two odd number it will always equal an odd number using algebra?

3x3=a That's just one example, though. You could switch it up saying: 3xa=9 or vice versa. It's kind of hard to depict it with algebra, but I think what I said before is pretty much what you would do.You can't prove it. Example: 3*9=27 You should try to prove something that is valid.

Prove using algebra that the sum of two consecutive whole numbers is always an odd number?

Let a=any integer. If a+(a+1)=2a+1. Any number multiplied by 2 will be even, and if we add 1 to this number, it will be an odd number.
