Question

write expresstion, in term of n, for the number oditi gets when she: adds 1 to the number

Answer 1

Answer:

Twice an odd number n is =2n, which is an even number, because if we multiply any number with 2 it will become even.

  ∙ The sum of 1 and twice an odd number n is =2n+1, which is always odd.

Hence, the expression for the sum of 1 and twice an odd number n is 2n+1, and will always be an odd number.

Step-by-step explanation:

Answer 2

Answer:

It will be 1 + n

Step-by-step explanation:

When we are adding we say '1 + n or n +1'

When we are subtracting  we say 'n - 1'

When we are multiplying we say '1n (To not get confused with the multiplication sign and the letter x)'

When we divide we say 'n / 1'
