Answer:
Here's how the sequence continues:
3^4 (3 multiplied by itself 4 times) = 81
3^5 (3 multiplied by itself 5 times) = 243
Step-by-step explanation:
The sequence you provided shows increasing powers of 3:
1, 3, 3², 3³, ..., 3^399
This is an exponential sequence where the base is 3 and the exponent increases by 1 for each term.
...
3^399 (3 multiplied by itself 399 times) - This is a very large number.
It's difficult to calculate the value of 3^399 by hand, but calculators can handle such large exponents.
