Answer:
A
Step-by-step explanation:
you move the a^1 to the left which becomes a^n-a^1. then you move (n-1) to the left as well which becomes a^n-a^1/n-1=d. you switch the places and tada, the answer.
Answer:
see below
Step-by-step explanation:
This is an arithmetic sequence. The explicit formula for an arithmetic sequence is aₙ = a₁ + (n - 1)d where a₁ is the first term and d is the common difference. In this case a₁ = 9 and d = 6 so we have:
aₙ = 9 + (n - 1) * 6
aₙ = 9 + 6n - 6
aₙ 6n + 3
It would be 55/100 but in simplest form it is now 11/20
