For this case, what we must do is calculate the mean of the given data.
For this, we must do the following:
Add the given numbers and divide by the number of numbers.
We have then:
$\frac{74+90+92+83+81+x}{6}=85$
From here, we clear the value of x.
We have then:
$x = 6 * 85 - (74 + 90 + 92 + 83 + 81)

x = 90$
Answer:
Tasha would have to score 90 on the sixth test to have a mean of 85
