Questions & Step-by-Step Solutions

If the sequence is defined by a_n = 3n + 1, what is a_4?
Correct Answer: 13
  • Step 1: Identify the formula for the sequence, which is a_n = 3n + 1.
  • Step 2: Substitute n with 4 in the formula to find a_4. So, we have a_4 = 3(4) + 1.
  • Step 3: Calculate 3 times 4, which is 12.
  • Step 4: Add 1 to the result from Step 3. So, 12 + 1 equals 13.
  • Step 5: Therefore, a_4 is 13.
