What is the 24th term of the sequence 3, 8, 13, 18?

To find the 24th term of the sequence 3, 8, 13, 18, we first need to identify the pattern in the sequence. The difference between consecutive terms is consistent:

  • 8 – 3 = 5
  • 13 – 8 = 5
  • 18 – 13 = 5

Each term increases by 5. This indicates that the sequence is an arithmetic sequence where:

  • First term (a) = 3
  • Common difference (d) = 5

The formula for the n-th term of an arithmetic sequence is:

Term(n) = a + (n – 1) * d

Substituting our values into the formula to find the 24th term:

Term(24) = 3 + (24 – 1) * 5

Calculating this gives:

Term(24) = 3 + 23 * 5

Term(24) = 3 + 115

Term(24) = 118

The 24th term of the sequence is 118.
