What is S10 for 1 + 3 + 9 + 27 +

The sequence is:

1, 3, 9, 27, ...

To find S10, we need to find the sum of the first 10 terms in the sequence. We can determine the pattern by observing that each term is 3 times the previous term:

1 * 3 = 3

3 * 3 = 9

9 * 3 = 27

So the sequence follows a pattern of multiplying by 3. Therefore, the 10th term is 27 * 3 = 81.

To find S10, we add the first 10 terms:

1 + 3 + 9 + 27 + 81 + 243 + 729 + 2187 + 6561 + 19683

S10 = 29524
