What is the middle term of an AP?

∴ Middle term of the AP. =(31+12)th term of the AP. = 16th term of the AP. ∴a16=6+(16−1)×7=6+15×7=6+105=111. Thus, the middle term of the given AP is 111.

What is the formula to find the middle term of an AP?

Hint:We find the position m of the middle term of the given AP using the formula m=(n+12). We then use the formula for the kth term of an AP which is xk=a+(k−1)d where a is first term and. We are given in the question that the AP has 23 terms.

How do you find the middle term of an AP if'n is even?

In arithmetic progression, the nth term is calculated by finding with the help of formula given as tn=a+(n−1)d. The formula for the middle term in case the n is odd is given by n+12. The formula for the middle term in case the n is even is given by the average of n2 and n+12 term.

Q55 | Find the middle term of the AP 213, 205, 197, ……., 37. | Arithmetic Progressions

How do you find the middle Most term?

Solution. The middle most term(s) of the AP: -11, -7, -3,.... 49 is 17, 21. As n is an even number, there will be two middle terms which are th 16 2 th and th, [ 16 2 + 1 ] th, i.e. the 8th term and the 9th term.

How do you find the middle term of AP 213 205?

Therefore, total number of terms is 23. Since, there are odd number of terms. So, Middle term will be ( 23 + 1 2 ) t h term, i.e., the 12^th term. Thus, the middle term of the A.P. 213, 205, 197, ...., 37 is 125.

What is the middle term of an AP 6 13 20 and 216?

Solution. The given AP is 6,13,20,........,216. Hence, the middle term of the given AP is 111.

What is middle term Factorisation?

Factorization by Splitting the Middle Term: The method of Splitting the Middle Term by factorization is where you divide the middle term into two factors. We know that composite numbers can be expressed as the product of prime numbers. For example, \(42 = 2 \times 3 \times 7\).

How do you find terms in AP?

Nth Term of an AP Formula

Therefore, the nth term of an AP (a_n) with first term “a” and common difference “d” is given by the formula: Nth term of an AP, a_n = a+(n-1)d.

What is splitting the middle term Class 10?

Splitting of the middle term is that we have to rewrite the middle term of the quadratic expression as the sum or difference of the two terms. We have to split the middle term into two parts in terms of sum or difference of the terms.

What is middle term in binomial theorem?

What Is the Middle Term in Binomial Theorem? The middle term in the binomial expansion depends on the value of n. The middle term and the number of middle terms depend on the value of n: n is even or odd. For an even value of n there is only one middle term and (n/2 + 1) term is the middle term.
