Math Problem Statement

Here is a sequence with a two-step term-to-term rule: Start at 6, multiply by 2, then add 3 each time. What is the next term in the sequence?

Solution

The problem involves a sequence with a two-step term-to-term rule:

  1. Start at 6.
  2. Multiply by 2, then add 3 each time.

Step-by-Step Solution:

  • First term (T₁): 66 (given).
  • Second term (T₂): 6×2+3=156 \times 2 + 3 = 15 (also given).
  • Third term (T₃): T2×2+3=15×2+3=30+3=33T₂ \times 2 + 3 = 15 \times 2 + 3 = 30 + 3 = 33

Thus, the next term in the sequence is 33.


Do you want further details on sequences or additional practice problems? Here are some questions for exploration:

  1. What would the fifth term in this sequence be?
  2. How does the two-step rule change if the "add 3" step is replaced with "subtract 3"?
  3. Can you write a general formula for the nth term in this sequence?
  4. How would the sequence look if the starting value were 10 instead of 6?
  5. Can you create a sequence with a similar rule but using division instead of multiplication?

Tip: When solving term-to-term sequences, carefully follow each step in the rule for accuracy!
