Answer 1

Mean=sum of all inputs /no.of inputs
18=(16+14+X+23+20)/5
90= 73+X
X=90-73
X=17
Hope it helps u definitely

Answer 2

Solution :-

Arithmetic Mean = Sum of all observation/Total number of observations

⇒ 18 =(16 + 14 + x + 23 + 20)/5

⇒ 18 = (73 + x)/5

⇒ (x + 73) = 18*5

⇒ x + 73 = 90

⇒ x = 90 - 73

⇒ x = 17

So, the value of x is 17
