Basic Mathematics QUESTION #7661
Question 1
In an Arithmetic Progression, if \(a_1 = 28\), \(d = -4\), \(n = 7\), then \(a_n\) is:
  • \(4\)✔️
  • \(5\)
  • \(3\)
  • None of these
Correct Answer Explanation
Using the formula \(a_n = a_1 + (n-1)d\), we have: \(a_7 = 28 + (7-1)(-4) = 28 + 6(-4) = 28 - 24 = 4\). Therefore, the 7th term of this arithmetic progression is 4.
