く usage in 場所は昨年と同じく、たから市民会館ホールです


> 本年もまたお願いいたした **く** 、ご連絡申し上げました。

What is the use of く here?

I think it is something like conjugating the verb to ます form then removing ます
to connect sentences.

For example:

> 交通ルールを守り、安全運転をしましょう.  
>  Let's follow the rule and drive safely.

But, in the sentences I mentioned above, it's an い-adjective and a な-adjective
(お願いいたしたい and 同じ). So, I would like to inquire about how this structure is
formed.

Is it:

Verb = conjugate verb to ます form then remove ます

い-adjective = conjugate to くて and remove て

な-adjective/Noun = add く after

PS. I got some great answers here [Removal of て in Japanese
novels](https://japanese.stackexchange.com/questions/70321/removal-
of-%e3%81%a6-in-japanese-novels/70324#70324) **but I'm not sure about this
同じく.**
