This is a very difficult question.

I don't know the answer.

Answer 2

Answer:

Here we have 3 terms in the series. So we should find the next two terms and should find the sum of the first 5 terms.

Answer: The sum of the first 5 terms $= 3 + 9 + 27 + 81 + 243=363$.

Step-by-step explanation:

• For find the next two terms, we should find logic between each terms in the series. Every term should be multiply by 3.
• First term => $1*3=3$

        2nd term => $3*3=9$

        3rd term => $9*3=27$

        4th term => $27*3=81$

        5th term => $81*3=243$

• Now we can find the sum of the first 5 terms.
• The sum of the first 5 terms $= 3 + 9 + 27 + 81 + 243=363$.
