Answer:
-14
Step-by-step explanation:
You've got a(1)=20
a(1) means a(n) when n=1
the sequence is telling you to take the previous value of a(n), which is a(n-1) and subtract 17
then:
a(2) = a(1)-17 = 20 - 17 = 3
a(3) = a(2) - 17 = 3-17 = -14

Answer:37 and half hrs
Step-by-step explanation:
This is what I get

40t=150
T= 150/4
T= 37.5
37hrs and 1/2
