.
1 = 5%5E0.

5 = 5%5E1.

25 = 5%5E2.

125 = 5%5E3.

Having this, you can easily continue your sequence as far as you want on your own.

Good luck !

Rule: highlight_green%28matrix%281%2C3%2C+a%5Bn%5D%2C+%22=%22%2C+5%5E%28n+-+1%29%29%29, with n being the term number.

Now use this rule to find what you need: the 5th, 6th, and 7th terms.
