Nicholas Chang · Answer 1

I think the answer is 8,10,12 because the set up would be 1) 2n

2) 2n+2

3) 2n+4 so then the equation is 6n+6=54 and when u solve the answer is 8. but then you also need the other two numbers so add 2 to 8 then add 2 to 10

Erica Daugherty · Answer 2

2n means 2 times n

so first divide 54 by 2

54/2 = 27

now you need 3 consecutive so 27/3 = 9

9*2 = 18

now use 1 number less and 1 number more

8*2 = 16

10*2 = 20

16 + 18+20 = 54
