Answer:
a(2) = -9
Step-by-step explanation:
It looks like you want the 2nd term in the arithmetic sequence defined by the recursive formula ...
- a(1) = -13
- a(n) = a(n -1) +4
Using the formula with n=2, we have ...
a(2) = a(1) +4
a(2) = -13 +4 . . . . substitute the value of a(1)
a(2) = -9

X-5y=36
x+y=-26
y=-26-x
x-5(-26-x)=36
x+130+x=36
2x+130=36
2x=36-130
2x=-94
