Please tell me how to write a cycle in PUG in a mixin that adds numbers to li classes?

Question

Pug

mixin li(img, title, p, liList)
.WorkingProcessContainer__li.WorkingProcessContainer__li#{liList}
i(.img, aria-hidden="true")
h5.ul__h5 #{title}
p.ul__p #{p}
a.ul__a # [i.fa.fa-plus(aria-hidden="true")] Know More
Can you please tell me how to write a loop that adds a value in the second line in liList? What classes would be
.WorkingProcessContainer__li WorkingProcessContainer__li1
.WorkingProcessContainer__li WorkingProcessContainer__li2
.WorkingProcessContainer__li WorkingProcessContainer__li3
.WorkingProcessContainer__li WorkingProcessContainer__li4
Thank you!
