To find the 23rd term (a23a_{23}) of the sequence, we can use the formula for the nth term of an arithmetic sequence:

an=a1+(n1)da_n = a_1 + (n-1) \cdot d

For n=23n = 23, a1=4a_1 = 4, and d=3d = 3, the formula becomes:

a23=4+(231)3=4+223=4+66=70a_{23} = 4 + (23 - 1) \cdot 3 = 4 + 22 \cdot 3 = 4 + 66 = 70

Thus, the 23rd term is a23=70a_{23} = 70.

Would you like further details or have any questions on this? Here are a few related concepts you might find interesting:

  1. How do you derive the formula for the nth term of an arithmetic sequence?
  2. What would happen if the common difference was negative?
  3. How can the sum of the first n terms of an arithmetic sequence be calculated?
  4. How does the formula for the nth term relate to other types of sequences, such as geometric ones?
  5. How would the sequence change if the first term was 0 instead of 4?

Tip: When calculating terms of an arithmetic sequence, always double-check the values of the first term, common difference, and the term number to avoid simple errors.
