How to find middle most terms of an AP?
Finding the Middle Most Terms of an AP
An arithmetic progression (AP) is a sequence of numbers where each term is obtained by adding a constant difference to the preceding term. To find the middle most terms of an AP, you need to know the total number of terms in the sequence and whether the number of terms is even or odd.
Step 1: Determine the Total Number of Terms
The first step in finding the middle most terms of an AP is to determine the total number of terms in the sequence. This can be done by counting the number of terms in the sequence or by using a formula:
n = (an - a1) / d + 1
Where:
- n = total number of terms
- an = last term in the sequence
- a1 = first term in the sequence
- d = common difference between terms
Step 2: Determine if the Number of Terms is Even or Odd
Once you know the total number of terms in the sequence, you need to determine if the number of terms is even or odd. This can be done by checking if the total number of terms is divisible by 2:
- If the total number of terms is even, then there are two middle terms.
- If the total number of terms is odd, then there is only one middle term.
Step 3: Find the Middle Most Terms
After determining the total number of terms and whether the number of terms is even or odd, you can find the middle most terms of the AP:
- If the number of terms is even:
- The middle two terms of the AP are:
- If the number of terms is odd:
- The middle term of the AP is:
a(n/2) and a(n/2) + d
a((n+1)/2)
By following these steps, you can easily find the middle most terms of an arithmetic progression.

How to find middle most terms of an AP?
If n is Odd, then the AP will have only one middle most term which will be the (n/2)th term. But if n is even, then the AP will have two Middle most terms and they will be (n/2)th term and (n/2 +1)th term.
