Therefore, we determine 4/a = 4/a is not proportion so, the answer is false.

Step-by-step explanation:

Since the difference is the same for each set, you can say that the common difference is 3. Therefore, you can say that the formula to find the common difference of an arithmetic sequence is: d = a(n) – a(n – 1), where a(n) is the last term in the sequence, and a(n – 1) is the previous term in the sequence.

please mark brainliestAnswer:4/a = 4/a

Cross multiplication:

32-a

16-a

We see that 16a are not equal to 32 a .

Therefore, we determine 4/a = 4/a is not proportion so, the answer is false.
