Answer: r= 25/3
Step-by-step explanation:
r-4(r+6)=-49 distribute the 4
r-4r-24=-49 combine like terms
-3r-24=-49 add 24 to both sides
-3r=-25 divide by -3
r= 25/3 answer
Given that

and

, if

is an arithmetic sequence, then the common difference between successive terms is

.
You then have




So the explicit formula for the

th term is
