How do you solve y=-4(-1) is for functions i don't understand how to solve it.

answer:

sequence is arithmetic (linear) and has constant rate of change of 0.8.

2.5, 3.3, 4.1, 4.9, 5. etc

step-by-step explanation:

you can generate the sequence of numbers by substituting f(n) with 2.5 to find the next number in the sequence.

2.5, 3.3, 4.1, 4.9, 5. etc

this sequence of numbers has a constant addition rate of change which makes it arithmetic. arithmetic sequences are known usually under their function name - linear.
