Questions & Step-by-Step Solutions

If the first term of a GP is 4 and the common ratio is 3, what is the product of the first three terms?
  • Step 1: Identify the first term of the GP, which is given as 4.
  • Step 2: Identify the common ratio of the GP, which is given as 3.
  • Step 3: Calculate the second term by multiplying the first term by the common ratio: 4 * 3 = 12.
  • Step 4: Calculate the third term by multiplying the second term by the common ratio: 12 * 3 = 36.
  • Step 5: List the first three terms of the GP: 4, 12, and 36.
  • Step 6: Calculate the product of the first three terms: 4 * 12 * 36.
  • Step 7: Perform the multiplication: 4 * 12 = 48, then 48 * 36 = 1728.
  • Step 8: The final answer is the product of the first three terms, which is 1728.
