Not sure if this is correct. But hope it helps! :)

But m must also be a multiple of 7, since it is mentioned that the five numbers are multiples of 7.
Better is “least m is 133” and “least value of fifth number is 147”.
In your case with 130 and 144, these are numbers separated by differences which are multiples of 7, but the five numbers themselves are not multiples of 7.

Oh yes, you are right, I hv missed that part. Thank you for pointing that out!
