(-1,-4) is where the equations Y=4x and x+y=-5 intersect.
No; we have . Substituting these into the DE gives
which reduces to , true only for .
Answer:
a(n) = -2 + 8(n - 1)
Step-by-step explanation:
General formula is a(n) = a(1) + d(n - 1), where d is the common difference.
Here a(n) = -2 + 8(n - 1)
