Write an expression for the sum of 1 and
twice a number 𝑛. If you let 𝑛 be any integer
number, will the result always be an odd
number? Explain.
Answer: 1 + 2𝑛
Always odd because the product of 2 and an even
number is always even but adding 1 makes it odd. And
the product of 2 and an odd number makes the
number always even but adding 1 makes it odd again.
