The sum of two consecutive odd integers is at least 16

Odd integers are represented by 2n+1 where n is a whole number

consecutive odd are 2 apart so

they are 2n+1 and 2n+1+2

the sum of them is at least 16

2n+1+2n+1+2>16

4n+4>16

minus 4

4n>12

divide 4

n>3

sub back

2n+1 and 2n+3

2 (3) + 1 and 2 (3) + 3

6+1 and 6+3

7 and 9

they have to be at least 7 and 9
