Answer:
5120
Step-by-step explanation:
The recursive formula ...
a[1] = 5
a[n] = 4·a[n-1]
defines a sequence with first term 5 and common ratio 4. The explicit formula for a term in this sequence can be written ...
a[n] = 5·4^(n-1)
We can use this formula to find a[6]:
a[6] = 5·4^(6-1) = 5·1024
a[6] = 5120
_____
If you like, you can write out the first 6 terms of the sequence using the recursive formula. Each is 4 times the previous.
5, 20, 80, 320, 1280, 5120, ...

Answer:
42°
Step-by-step explanation:
Therefore,
(2y + 2)° = (3y - 18)°
2y + 2 = 3y - 18
2y - 3y = - 2 - 18
-y = - 20
y = 20
