Percent Error =

So, Ari's experimental value is ,

The accepted value is,

Here's The Work

Ari's Average Measurements Have An Percent Error Of 2.26%
<span>Let z be the percent of the cup that is oats.
Therefore 310*z + 290 * (1-z) = 302.
310z-290z+290=302.
20z=12
z=12/20 = .6.
Therefore the new cereal is 60% oats and 40% wheat flakes.
A cup of the cereal then contains 3/5 cup of oats, and 2/5 cup of wheat flakes.</span>

nth term is: 
122 is not in the sequence
Further explanation:
First of all we have to decide whether it an arithmetic sequence or geometric sequence,
Here


As the common difference is same for all consecutive terms, the sequence is an arithmetic sequence
The formula for arithmetic sequence is given by:

Here a_n is the nth term
a1 is the first term
n is the term number and
d is the common difference
Putting the value of a1=4 and d=6 in the formula

To check whether 122 will be number in the sequence or not,
Putting the value in nth term we will find the value of n, if n is an integer then 122 is a part of the sequence, otherwise not
So,

As the value of n is in decimal, that means none of the terms in the sequence is 122.
So,
nth term is: 
122 is not in the sequence
