Find the 5th term of the AP: -8, -12, -16, ...
Explanation
Explanation
The nth term of an AP is aₙ = a + (n-1)d, where a = -8 (first term) and d = -4 (common difference). So the 5th term = -8 + (5-1)(-4) = -8 + -16 = -24.
PRO TIP
Re-check your working by substituting the answer back into the original question.
