common difference, d = -3

f1 = -13

An arithmetic sequence f(n) = f1 + d(n - 1)

so f(n) = -13 - 3(n - 1)

f(46) = -13 - 3(46-1) = -13 -3(45) = -13 - 135 = -148

Answer:

f(46) = - 148

Answer: 0.03 and 0.4

Step-by-step explanation:

3.0 would turn into 3.

3 divided by 100 is 0.03.

20 divided by 50 is 0.4
