Complete the Number Sequence: Finding the Pattern Starting with 5, 7

Question

Complete the following sequence:

5,7 5,7\ldots

Step-by-Step Solution

To solve this problem, we'll identify whether the sequence follows a recognizable pattern. The sequence so far is 5,75, 7.

Let's determine whether it follows an arithmetic sequence:

  • First Term (a1a_1) = 5
  • Second Term (a2a_2) = 7
  • The Common Difference (dd) = 75=27 - 5 = 2

Assuming a consistent common difference, the sequence appears to be an arithmetic sequence increasing every term by 2.

Let's calculate the next few terms:

  • Third Term (a3a_3) = 7+2=97 + 2 = 9
  • Fourth Term (a4a_4) = 9+2=119 + 2 = 11
  • Fifth Term (a5a_5) = 11+2=1311 + 2 = 13

Thus, the full sequence is: 5,7,9,11,135, 7, 9, 11, 13.

A review of the multiple-choice options shows that the correct answer is given by choice 1: 5,7,9,11,135, 7, 9, 11, 13.

Therefore, the complete sequence is 5,7,9,11,135, 7, 9, 11, 13.

Answer

5,7,9,11,13 5,7,9,11,13
