Question:
In Hepta-3,5-dien-1-yne, how is the numbering done? I'm confused as alkene has more priority than alkyne.
Answer:

Alkenes and alkynes are considered to have equal priority. In a molecule with both a double and a triple bond, whichever is closer to the end of the chain determines the direction of numbering. In the case where each would have the same position number, the double bond takes the lower number.
