Rewrite the fractions to have a common denominator to find the difference:
2/3 = 4/6
Difference = 4/6-5/6 = -1/6
Sequence formula = an = a1 + d(n-1)
A1 is the first term 5/6
And d = -1/6
Sequence = 5/6 -1/6(n-1)
Simplify to get an =(-n +6)/6
5 + 27 ÷ 3 / 6 + 1 - Remember PEMDAS, so start by dividing 27 by 3.
5 + 9 / 6 + 1 - Next, add
14 / 7 Lastly, Divide.
