Apply Service pack from Sql Server 2016 SP2 to Sql server 2016 SP3

Hello,
I will appreciate your help for following question.
We need to Service pack for pour Sql Server 2016 which is currently on Microsoft SQL Server 2016 (SP2-CU7-GDR) (KB4505222) - 13.0.5366.0 (X64) and need to update SP3 latest pack.

Can I know How many SP and CU version I need to apply?

I know that in Sql 2017, we can apply latest CU and it can covered all SP/CU's so don't need to apply one by one but in Sql 2016 what's the path I have to follow?

If I see the SP's and CU's from my current version of SP2 then I found following so getting confused that I need to apply SP + CU all below listed?

Generally the latest service pack plus any subsequent patches should be applied. GDRs are not cumulative as far as I know, so if you want to be fully covered I suggest installing all of the ones listed after SP3.

You seem to have posted the list of KBs describing the latest available:

Robert,
Thanks for your detail answer with the link, much helpful.
So you mean to say, I have currently SP2 - CU7 so I can directly apply first SP3 13.0.6300.2 then all other SP3's?
SP3 + GDR 13.0.6435.1 KB5029186
SP3 + GDR 13.0.6430.49 KB5021129
SP3 + GDR 13.0.6419.1 KB5014355
SP3 13.0.6300.2 KB5003279

Yes, install SP3 first (that is cumulative, it will have everything after your current patch level) and as many of the subsequent GDRs as you feel are necessary afterward.

Robert,
Thank you it was very much helpful, clear the doubts and made the patch apply path very easy.
Appreciate your help!
