N refers to the number of terms.

Answer 2

Answer:

• Median of a series of data values is denoted that way by tilde on top of a letter.

Step-by-step explanation:

• The operator tilde (~) on top of a variable that denotes a vector or a set of values or a mathematical set represents usually the median value of the series of data values. This median is the median in statistics that represents an approximate mid value of the data set.. We know mean, median and mode, right ? That median.  

• If there are N number of data values in a data set n , then  
• ñ = the (N+1)/2 th data value if N is odd,  
• = the average of the N/2 th and (N+2)/2 th data values if N is even.  

For example:  

n = {4, 2, 6, 9, 7, 10, 3 }  

ñ = 9 = median of variable n as it is the 4 th value (N = 7).  

Further, ñ has more meanings.  

• The tilde operator on top of capital D means the differentiation operator d/dx which is extensively used in mathematics, sciences and even in macro economics.

• The tilde operator on top of an alphabet represents a new operation defined by a scientist or engineer for his data set of values. That symbol is used in many research papers in that way.
