The element being searched for is not found in an array of 100 elements. What is the average number of comparisons needed in a sequential search to determine that the element is not there, if the elements are completely unordered?

• 100
  let us assume k be the element we need to search
  then let array be n1,n2,n3..............n100
  now to prove that the element searched is not there in the array we have to compare the element K with every element in the array.
  So,totally we need 100 comparisons.

• 100
  Because we have to compare each element

• 99
  in order to compare n things those are not in a particular order, n-1 comparisions are necessary

• It will take order of n times
