Using similar triangles to find an unknown value. what is the value of x?

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000

What is the recursive formula for this sequence . 10,14,18,22,26
