Question 7 2 Points In this question we will follow the example in the reading to identify and describe a pattern in this list of numbers.2,5, 8, 11, ... a. Use the pattern to find the next number in the list Blank 1 b. Use the pattern to find the 12 th number in the list Blank 2 c. Find a forrgula for the \( n \)th number in the list. Blank 3. Hint: Start with \( n=1 \) so you will have \( (n-1) \) in your answer. Blank 1 \( \square \) Add your answer Blank? Adti vour answer

a. The next number is 14.
b. The 12th number is 35.
c. The formula for the nth number is \( a_n = 3n - 1 \).
Solución
We are given the arithmetic sequence: 2, 5, 8, 11, …
a. Since the difference between consecutive numbers is 3 (i.e., 5 – 2 = 3, 8 – 5 = 3, etc.), the next number is:
11 + 3 = 14
b. To find the 12th number, use the arithmetic sequence formula:
aₙ = a₁ + (n – 1) × d
Where a₁ = 2, d = 3, and n = 12.
a₁₂ = 2 + (12 – 1)×3 = 2 + 33 = 35
c. To find the general formula for the nth term:
aₙ = 2 + (n – 1)×3
This can be simplified to:
aₙ = 3n – 1
So, the answers are:
Blank 1: 14
Blank 2: 35
Blank 3: aₙ = 2 + 3(n – 1) or equivalently aₙ = 3n – 1.

The pattern in the given sequence—2, 5, 8, 11—shows that each number increases by 3. So to find the next number, you simply add 3 to the last number (11). Therefore, the next number is 11 + 3 = 14! Now, for the 12th number in the list, you would keep adding 3 starting from 2. The formula for the \( n \)th number would be \( 2 + (n - 1) * 3 \). Thus, when \( n=12 \), it will be \( 2 + 11 * 3 = 35 \). Happy calculating!
