Is the number 30 a term in the sequence?

Video Solution

Solution Steps

00:06 Is the number thirty a part of the sequence?
00:10 Let's put the number into the sequence formula and find N.
00:15 If N is a positive whole number, that's its spot in the sequence.
00:20 Now, we'll solve for N carefully.
00:31 And that's how we find the answer. Great job!

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Use the sequence rule to form the equation 6n=306n = 30.
  • Step 2: Solve the equation for nn.
  • Step 3: Determine if the solution is a positive integer and identify the term position.

Now, let's work through each step:
Step 1: Set up the equation using the rule of the sequence: 6n=30 6n = 30 .
Step 2: Solve for nn by dividing both sides by 6:
n=306=5 n = \frac{30}{6} = 5 .
Step 3: Since n=5n = 5 is a positive integer, 30 is a term in the sequence, specifically the fifth term.

Therefore, the solution to the problem is Yes, it is the fifth term.

Answer

Yes, it is the fifth term.
