For the arithmetic sequence
a₁, a₂, a₃, ...,
The n-th term is

where d = common difference.
Because a₁₀ = 41,
a₁ + 9d = 41 (1)
Because a₁₅ = 61
a₁ + 14d = 61 (2)
Subtract (1) from (2).
5d = 20
d = 4
From (1), obtain
a₁ = 41 - 9*4 = 5
Therefore
a₃ = 5 + 2*4 = 13
Answer: a₃ = 13

X = $20 bills
6x = $5 bills
x(20) + 6x(5) = 1450
20x + 30x = 1450
50x = 1450
x = 29
6(29)= 174
Answer:
As a decimal it can be written as 7.3 repeated
