Question 58

The median of the first seven prime numbers is:

Solution

first, seven prime numbers are 2, 3, 5, 7, 11, 13, 17.

Here the number of terms are 7. So n = 7.

median = $$\left(\frac{n+1}{2}\right)^{th}\ term$$

= $$\left(\frac{7+1}{2}\right)^{th}\ term$$

= $$\left(\frac{8}{2}\right)^{th}\ term$$

= $$4^{th}\ term$$

= 7
