There are three things needed in order to find the 35th term using the formula:
the first term ( {a_1}a
1
)
the common difference between consecutive terms (dd)
and the term position (nn )
Step-by-step explanation:
Therefore, the known values that we will substitute in the arithmetic formula are
a sub 1 equals 3, common difference is 6, term position or n is 35
So the solution to finding the missing term is,
