Answer 2

Answer:

2,7,12,17

Step-by-step explanation:

In an AP if the terms are

a, b,c,d......

And you have given a & c then you could get b by finding the arithematic mean of a & c

i.e.,

b=(a+c)/2

When you will get b then easily you can find the common difference of the AP and it will become very easy for you to find any term of that AP.
