10 adults + 5 children = $75 ------------- (1)
8 adults + 10 children = $78 ------------- (2)
(1) x 2 : 20 adults + 10 children = $150 ------------- (1a)
(1a) - (2) : 12 adults = $72
1 adult = $6
Substitute 1 adult = $6 into (1):
10 ($6) + 5 children = $75
$60 + 5 children = $75
5 children = $15
1 child = $3
Therefore 1 adult = $6 and 1 child = $3
Find 6 adult and 10 children:
6 adults + 10 children = 6(6) + 10(3) = 36 + 30 = $66

Answer:
8th term is 3980.
Step-by-step explanation:
0 12 72 240 598 1250 2322
Differences in successive terms
are:
12 60 168 358 652 1072
48 108 190 294 420
60 82 104 126
22 22 22
So calculating the 8th term , working from the last line to the first:
126 + 22 = 148
148 + 420 = 568
1072 + 568 = 1658
Finally the 8th number = 2322 + 1658 = 3980
