Pls give answer to my question
an answer will come when someone who feels able to answer it comes online.
Repeating the request will not make them show up any sooner.
So. On to the question. Use the formulas you know. That means
a+d = -6
a+4d = 48
subtract the top from the bottom, and you have
3d = 54
d = 18
so a = -24
Now, you know that
S4 = 4/2 (2a+3d)
So plug and chug.
