Answer:

Step-by-step explanation:
We are given that:
First term (a) = 5
common ratio (r) =
The nth term of a geometric sequence is given as:

X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
