Answer:
We need to find the first term. We can use the formula
an = a1 + d(n - 1)
to solve for a1. We already know the 12th term, a12, common difference, d, and nth sequence, n.
a12 = -36
d = -4
n = 12
-36 = a1 - 4(12 - 1)
-36 = a1 - 44
8 = a1
The first term is 8. Therefore, your formula is
an = 8 - 4(n - 1)
an = -4n + 12
Then use this formula to graph.
n is the independent variable.
an is the dependent variable.
Your graph will be a line.
n | an

Answer:
£ 21552.13
Step-by-step explanation:
P= £18790
r =4.9% = 
t = 3 years
I = Prt
I = 18790 * 0.049 * 3
=£ 2762.13
After 3 years , the amount in Dan's account = 18790 + 2762.13
= £ 21552.13
