Question

Given the arithmetic sequence where a1=-5 and d=6 what is a5? please help

Answer 1

do u know the formula of for finding n-th term?

Answer 2

if \(a_n\) is the nth term of a sequence with first term \(a_1\) and common diffrence \(d\) then
\[a_n=a_1+(n-1)d\]

Answer 3

now put n=5 then u'll get
\[a_5=a_1+(5-1)d=a_1+4d\]
now just plug the values of a1 and d

Answer 4

got that?
