Hi,this is the statistics i have

dv_cmdb_ci  number  _time   state

1 A B 2018-04-03 15:00:51 Assigned
2 A B 2018-04-03 15:03:28 Work in Progress
3 A B 2018-04-03 18:09:46 Work in Progress
4 A B 2018-04-03 18:11:36 Assigned
5 A B 2018-04-03 18:14:53 Assigned
6 A B 2018-04-03 18:22:14 Work in Progress
7 A B 2018-04-03 18:51:07 Work in Progress
8 A B 2018-04-03 18:57:26 Work in Progress
9 A B 2018-04-03 19:18:41 Work in Progress
10 A B 2018-04-04 17:25:59 Work in Progress
11 A B 2018-04-04 17:26:25 Pending
12 A B 2018-04-19 16:18:43 Resolved
13 A B 2018-04-22 17:00:07 Closed

This is for single host and single ticket data.

How can i get the time difference when ticket was in pending to Resolve.

From above based on state my time difference should be (2018-04-19 16:18:43)-(2018-04-04 17:26:25)=difference in second.

So how to calculate it????

Like this:

Your Search Here:
| search (state="Pending" OR state="Resolved")
| stats range(_time) AS duration BY number
| eval duration=tostring(duration, "duration")

Another approach (A generic one which allows finding duration between any two states)

your base search 
| eval temp=dv_cmdb_ci."##".number
| chart max(_time) over temp by state
| rex field=temp "(?<dv_cmdb_ci>.+)##(?<number>.+)" | fields - temp
| table dv_cmdb_ci number *

Above will give time for each state for a host-ticket combination as a column. You can now add eval statements to find duration between any two states, by adding it to end of above search, e.g.

above search
| eval PendingToResolvedDuration=Resolved-Pending

Any state value which has spaces in them, enclose them in single quotes. (e.g. | eval WIPtoResolved=Resolved-'Work In Progress')

Or like this (gives you options to do any kind of state-change timing all together, which the other answer does not):

Your Search Here
| eval PendingTime=if(state="Pending", _time, null())
| eventstats min(PendingTime) AS PendingTime BY number
| eval PendingToResolvedTime = if(state="Resolved", tostring((_time - PendingTime), "duration"), null())

In your base search add (state="Pending" OR state="Resolved"), then use the transaction command as follows:

| transaction <field(s) to group by> startswith="Pending" endswith="Resolved"

The transaction command automatically gives you a "duration" field in seconds.

Hope this helps

True, but one should NEVER use transaction if there is ANY other way. In this case there is. The overhead and unscalability of transaction means that it should be avoided at all costs.
