Questions & Step-by-Step Solutions

What is the 10th term of the arithmetic sequence where the first term is 5 and the common difference is 3?
  • Step 1: Identify the first term of the sequence, which is given as 5.
  • Step 2: Identify the common difference of the sequence, which is given as 3.
  • Step 3: Identify the term number we want to find, which is the 10th term (n = 10).
  • Step 4: Use the formula for the nth term of an arithmetic sequence: a_n = a + (n-1)d.
  • Step 5: Substitute the values into the formula: a_10 = 5 + (10-1) * 3.
  • Step 6: Calculate (10-1) which equals 9.
  • Step 7: Multiply 9 by the common difference (3): 9 * 3 = 27.
  • Step 8: Add this result to the first term: 5 + 27 = 32.
  • Step 9: Conclude that the 10th term of the sequence is 32.
