m is an odd integer. For each of the following numbers, indicate whether the number is odd or even.

Solution

if mis odd let us assume the value of mis 5 then

a)2m-1=2(5)-1=10-1=9 the number is odd

b) 2m+1= 2(5)+1=10+1=11, the number is odd

c) m² -m= (5)² -5=25-5=20, the number is even

d) m² +m+1=5² +5+1= 25+5+1=30+1=31,the number is odd.
