Substitute n with 4 to find d(4):
d(4)=d(4-1)+17
d(4)= d(3)+17=47+ 17= 64
Substitute n with 3 to find d(3):
d(3)= d(2)+17=30+17 =47
Substitute n with 2 to find d(2):
d(2)=d(1)+17= 13+17= 30
The 4th term is 64
Answer:
x = 19
Step-by-step explanation:
x = the number
The words translate into algebra as
4x + 25 = 6x - 13
Solve for x.
25 + 13 = 6x - 4x
38 = 2x
x = 19
A=p(1-0.12)^t
A=45×(1−0.12)^(1)
A=39.6
