An arithemetic sequence has 15 terms what is the position of middle term in the order lines of terms
Answers
Answer: This may help you
Step-by-step explanation:
Arithmetic Progression (AP) is a sequence of numbers in order in which the difference of any two consecutive numbers is a constant value. For example, the series of natural numbers: 1, 2, 3, 4, 5, 6,… is an AP, which has a common difference between two successive terms (say 1 and 2) equal to 1 (2 -1). Even in the case of odd numbers and even numbers, we can see the common difference between two successive terms will be equal to 2.
If we observe in our regular lives, we come across Arithmetic progression quite often. For example, Roll numbers of students in a class, days in a week or months in a year. This pattern of series and sequences has been generalized in Maths as progressions.
Answer:
The middle term is the 8th term
Step-by-step explanation:
The Number of terms is odd so use the formula
n is the number of terms
formula: n+1/2 so in this problem its 15 terms so 5+1/2= 16/2=8.
If the number of terms is even say 74 use the formula: where n is number of terms
formula: n/2, n+1/2 so in the problem its 74 terms so 74/2, 74+1/2
= 37th ,38th values are the middle values...
Hope u understood....
