Hi Sonal,
If your goal is to apply filters/pagination on tasks in a list this should help -
https://graph.microsoft.com/v1.0/me/todo/lists/[ListID]/tasks?$skip=2.
if you are filtering tasklist since the $skip is not yet available for to do List api you can try - https://graph.microsoft.com/v1.0/me/todo/lists?$filter=startsWith(displayName,'M')
in general for pagination please refer doc here - https://learn.microsoft.com/en-us/graph/query-parameters#filter-parameter
Also, to enable $skip query param on to do lists please create a new ask here on user voice - https://microsoftgraph.uservoice.com/forums/920506-microsoft-graph-feature-requests?category_id=373861
