Question

Find the indicated term of the arithmetic sequence with first term a 1and common difference d. Find a 6​, when a 1equalsnegative 50​, and dequalsnegative 3. a 6=?

Answer 1

a6=?
a1=-50
d=-3

an=a1+(n-1)d
n=6→a6=a1+(6-1)d
a6=a1+5d
Replacing a1=-50 and d=-3
a6=-50+5(-3)
a6=-50-15
a6=-65

Answer: a6=-65
