To find the output when the input is x = -3 for the function f(x) = 2x - 1, you simply plug in the value of x into the function and solve for f(x).

f(-3) = 2(-3) - 1
f(-3) = -6 - 1
f(-3) = -7

Therefore, the output when the input is x = -3 is -7.

To find the common difference of an arithmetic sequence, we subtract two consecutive terms in the sequence.

In the given sequence: 50, 46, 42, 38, ...

To find the common difference, we can subtract each term from the previous term.

46 - 50 = -4
42 - 46 = -4
38 - 42 = -4

Therefore, the common difference of the arithmetic sequence 50, 46, 42, 38, ... is -4.
