What is the smallest number if the sum of four consecutive numbers is 448?

if they were all the same, they'd each be 112

110+111+112+113 = 446
Now you have a problem. I suspect a typo

It would work if you meant 4 consecutive even numbers ...

x + x+2 + x+4 + x+6 = 448
4x = 436
x = 109 , ahhh, but that number is NOT even, so it can't be that

How about 4 consecutive odd numbers ???

same setup and solution
x = 109
the numbers are 109, 111, 113, and 115 for a sum of 448
