yulyashka [42]

Answer:

Step-by-step explanation:

{0, -8, -16, -24,...} here you add -8 each time so the rule is

$a_{1} = 0, a_{n} = a_{n-1} -8$

the 71 term is

$a_{71} = 0 + (71 - 1) * (-8) = 70 * (-8) = -560$

If a adult ticket is 5$ and a student ticket is 1$ the total money collected is 2,662 and the sold ticket is 1,198

PIT_PIT [208]

5a + s = 2662
a + s = 1198
4a = 1464
a = 366

5(366) + s = 2,662
1830 adult tickets sold

2662 - 1830 = 832
832 student tickets sold
