Can you update an iPad A1395

No.

An iPad 2 is an over 8-1/2-year old iPad, now!

Its internal hardware is much too old and woefully underpowered to be able to run any later iOS versions.

Time to consider purchasing a new or discounted, refurbished iPad from Apple.

Best of Luck to You!

No. Its maximum iOS version is 9.3.5.
