Find an explicit function rule for the sequence 5, 11, 17, 23, .... Use the formula a (n) = a (1) + (n-1)d and simplify fully.

Verified Answer :

naǫ

\(5,11,17,23,... \\ \\ a_1=5 \\ d=a_2-a_1=11-5=6 \\ \\ a_n=a_1+d(n-1) \\ a_n=5+6(n-1) \\ a_n=5+6n-6 \\ a_n=6n-1\)

The function rule for the sequence is a(n)=6n-1.

Answer:

an=−1+6n
