Find the 6th term term of the arithmetic sequence 8,5,2,-1

The 6th term is -7. the common difference is -3.

Sritmetic
an=a1+d(n-1)
a1=first term
d=common difference
n=which term

first term is 8
2nd is 5, so common differnce is -3

an=8-3(n-1)
for 6th term
an=8-3(6-1)
an=8-3(5)
an=8-15
an=-7

te 7th term is -7
