Answer:
= 5n - 2
Step-by-step explanation:
The terms have a common difference between consecutive terms, that is
8 - 3 = 13 - 8 = 18 - 13 = 5
This means the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference, thus
= 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2
Answer:
y = 20
x = 120
Step-by-step explanation:
2x + 3y = 300
3x + 5y = 460
mutliply eqn 1 by 3 and 2 by 2
6x + 9y = 900
6x + 10y = 920
y = 20
x =
the answer is 0 its like 14-14=0
