Find the 6th term of the AP: -6, -11, -16, ...
Explanation
Explanation
The nth term of an AP is aₙ = a + (n-1)d, where a = -6 (first term) and d = -5 (common difference). So the 6th term = -6 + (6-1)(-5) = -6 + -25 = -31.
PRO TIP
Re-check your working by substituting the answer back into the original question.
