You need to know these two formulas:

$\huge a^b \times a^c = a^{b+c}\\\\\huge \frac{a^b}{a^c}=a^{b-c}$

For example,

$5^2 \times 5^3 = 5^{2+3} = 5^5$

$\frac{2^6}{2^4} = 2^{6-4} = 2^2$

Semmy [17]

Answer:

an = 5 + 10(n -1)
a7 = 65

Step-by-step explanation:

The explicit formula for the n-th term of an arithmetic sequence is ...

an = a1 + d(n -1)

where a1 is the first term and d is the common difference.

The sequence of seat counts has a1=5 and d=10, so the explicit formula is ...

an = 5 +10(n -1)

___

The 7th term is ...

a7 = 5 +10(7 -1) = 65
