Whose 11th term is 38 and 16th term is 73 find the common difference and first term of an AP?

The 31st term of an AP whose 11th term is 38 and the 16th term is 73 is 178.

What is the 11th term of an arithmetic sequence?

Correct answer: \displaystyle -9. Explanation: The common difference of the sequence is the difference of the tenth and ninth terms: \displaystyle d = 99-87 = 12. The ninth term of an arithmetic sequence with first term and common difference is , so we set this equal to 87, set , and solve: \displaystyle a + 8d = 87.

What is the 31st term of an AP whose 11th term is 38 and 16 term is 73?

178
whose 11th term is 38 and the 16th term is 73. Hence, 31st term is 178.

What is the 16th term of an AP whose first two terms are 100105 *?

16th term of an AP is 175.

How do you find the 11th term of AP?

Hint: To find 11th term from the end we will approach same as we are doing from first term only we have to take last term as the first term and the common difference is previous term minus the next term and take n equal to 11 and calculate the value of 11th term by using the nth term formula in AP.

What is the 31st term of an AP?

Therefore, the 31st term of AP is 178.

What is the meaning of AP 3 11 19?

Therefore 69 th term is 547.

What is the 31st term of an AP whose 11th term is 38?

Find the 31 st term of an AP whose 11 th term is 38 and the 16 th term is 73. 38=a+10d (i) 73=a+15d (ii) Hence, 31 st term is 178. Was this answer helpful?

How do you find the sum of arithmetic progressions?

To find the sum of arithmetic progression, we have to know the first term, the number of terms and the common difference between each term. Then use the formula given below: S = n/2 [2a + (n − 1) × d] What are the types of progressions in Maths?

What is the formula to find the nth term of arithmetic progression?

The arithmetic progression general form is given by a, a + d, a + 2d, a + 3d,…. Hence, the formula to find the nth term is: an = a + (n – 1) × d What is arithmetic progression?

What is the abbreviation for arithmetic progression?

Arithmetic Progression (AP) Geometric Progression (GP) Harmonic Progression (HP) A progression is a special type of sequence for which it is possible to obtain a formula for the nth term. The Arithmetic Progression is the most commonly used sequence in maths with easy to understand formulas.
