-914

Step-by-step explanation:

f (n) = -5f (n-1) - n

f (2) = - 5f (1) - 2 = - 5 (7) - 2 = - 37

f (3) = - 5f (2) - 3 = - 5 (-37) - 3 = 182

f (4) = - 5f (3) - 4 = - 5 (182) - 4 = - 914

If f (1) = 7 and f (n) = -5f (n-1) - nthen find the value off (4)

If f (1) = 7 and f (n) = -5f (n-1) - n

then find the value of

f (4)
