What is the arithmetic sequence between 2 and 10?

1, 4 and 7.

How do you find the arithmetic mean between 9 and 49?

Detailed Solution

  1. Given: Arithmetic mean of 9 terms = 49. Mean of first 7 terms = 37.
  2. Formula Used: Mean = Sum of terms/Number of terms.
  3. Calculations: Let sum of last 2 terms be x. Sum of all 9 terms = 49 × 9. ⇒ Sum of all 9 terms = 441.
  4. ∴ The mean of last 2 terms is 91. Download Soln PDF. Share on Whatsapp.

How is arithmetic sequence formed?

An arithmetic sequence is a sequence where consecutive terms are calculated by adding a constant value (positive or negative) to the previous term. We call this constant value the common difference (d).

What is a arithmetic sequence in math?

An arithmetic sequence is a sequence of numbers which increases or decreases by a constant amount each term. Once you know the common difference, you can find the value of c by plugging in 1 for n and the first term in the sequence for a1 . Example 1: {1,5,9,13,17,21,25,…}

What is arithmetic sequence in math?

An arithmetic sequence or arithmetic progression is a sequence in which each term is created or obtained by adding or subtracting a common number to its preceding term or value. In other words, the difference between the adjacent terms in the arithmetic sequence is the same. Formulas of Arithmetic Sequence.

How do you find the number of terms in a sequence?

S n = n/2 (first term + last term) Where, a n = n th term that has to be found. a 1 = 1 st term in the sequence. n = Number of terms. d = Common difference. S n = Sum of n terms. A few solved problems on the arithmetic sequence are given below.

What is the difference between N and D in arithmetic sequence?

n = the number of terms. d = the common difference. S n = the sum of n terms. A solved problem on the arithmetic sequence is given below.

How to write an explicit formula for the term of arithmetic sequence?

An explicit formula for the term of an arithmetic sequence is given by Given the first several terms for an arithmetic sequence, write an explicit formula. Write an explicit formula for the arithmetic sequence. The common difference can be found by subtracting the first term from the second term. The common difference is 10.
