Answer:
Step-by-step explanation:
A_n = a + (n-1)d
a_n = -2n + 3
when n=1
a_1 = a = -2(1) + 3 = -2 + 3 = 1
when n = 2
a-_2 = -2(2) + 3 = -4 +3 = -1
a_2 = a + d
therefore,
a + d = -1
d = -1 - a
d = - 1 - 1
d = -2
Therefore the sequence is ,
1 , -1, -3, -5, -7.......

So the total money is:
x + (x-50) + (x-100).
