In numerology, the number 7 and the number 17 have quite different meanings. As does the number 717.

Number repetition does make a difference, as in the case of the 7's in the number 717. But it does not alter the basic meaning of 717.

The number 7 is a number of introspection. It finds answers within.

The number 17 reduces to the basic vibration of the number 8, a number of organization. It can also be good with finances.

The number 717 reduces to the basic vibration of the number 6. The number 6 is a number of family and harmony. It is also a healer. The repetition of the number 7 within 717 suggests introspection within family, harmony, and healing.

Your life cycle number from birth through year 2010 was the number 7. It will have been a period of introspection, even as a child.

Your current life cycle number, through year 2037, is the number 8 (the same basic vibration as the number 17). You are beginning a period of organization, perhaps being or becoming the chief operating officer of a corporation, and will tend to be better at handling money.

One of your challenge numbers is the number 6 (the same basic vibration as the number 717). Home and harmony tend to be a challenge for you and, until you accept the fact, may feel like you are unduly burdened. Acceptance is the difference between a negative and a positive outlook. With a positive outlook, more positive things happen.

The 7, 8 (17), and 6 (717) being embedded in your life cycle and challenge numbers I think is synchronous rather than portentous.
