Is the sequence if so identify the common difference

A) Yes, 7

Step-by-step explanation:

The given sequence  An = {13, 20, 27, 34, ...}

Here the first term Ao = 13 and difference between the successive terms is (d) = 7

That is  d = 20  - 13

d = 7

It is an arithmetic sequence. d = 7

Yes, it is arithmetic sequence and common difference (d) = 7

Thank you.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
