Is there a specific or odd number for the glorification in bowing and prostrating?

It is recommended for the worshiper, whether an Imam or otherwise, to glorify Allah during their bowing (rukūʿ) and prostration (sujūd). So, in their bowing, they should say: "Subḥāna Rabbī al-ʿAẓīm (Glory be to my Lord, the Most Great)," and in their prostration: "Subḥāna Rabbī al-Aʿlā (Glory be to my Lord, the Most High)," following the example of the Prophet, peace and blessings be upon him. One should not neglect this, and it is preferable for the glorification to be an odd number (witr) rather than an even number (shafʿ).
