how can we get start parameter for particular pageNumber without using nextPageStart parameter

[Siyaram Meena]

In bitbucket data Center REST API searching for Repositories
I have pageNumber and itemPerPage(limit).
i want to calculate the start index for that page without using nextPageStart.


for example if i set pageNumber - 10 without visiting previous page for that do i have get start from previous response (pageNumber 9) nextPageStart parameter.
for pageNumber-9 it will check in previous page. this will continue till i will not visiting its all previous page?
