Practice This ConceptMain explanation
Teacher explanation
When the number of terms in an AP is odd, the middle term is the term at the center. In a well-balanced AP, the middle term is also the average of the first and last terms when the terms are arranged symmetrically.
Example
In 2, 5, 8, 11, 14, the middle term is 8.
Simple analogy
Middle means same number of terms on both sides.
Common confusion
Students sometimes call the third term the middle term without checking whether the sequence has an odd number of terms.
Exam tip
First count the total number of terms. Only then decide which one is in the middle.
