Make two equations
C = children, A = adults
2.50C + 7.00A = 7950
(C + A = 2100) * 2.5
2.50C + 2.50A = 5250
Use elimination
4.5A = 2700, A = 600
2100 - 600 = 1500
Solution: 600 adults, 1500 children
Answer : 28, 23, 18
To find the ‘nth term’ all you have to do is replace the variable ‘n’ in the equation with the number term you’re looking for.
In this case you’re looking for the first three terms, so you would replace n with the numbers 1, 2, and 3.
This gives you 28, 23, and 18.
