Question

pls solve! Find the median of first 40 whole numbers. write answer =19.5​

Answer 1

Answer:

sum of natural no. is n(n+1)/2

but we have whole no. here so it means we have to add 39 no.s and 0 .

so sum of first 39 no.

39(40)/2=780

780+0= 780

mean = 780/40 = 19.5

median = if we have even no. of series we have

median = (nth/2 + (nth+2)/2 )÷2

(20th + 21th )÷2 = (19+20)/2

19.5
