Q1 of 67 Page 74

The common difference of two arithmetic progression is the same. The first term of one of them is 8 and of the second is 3. Then difference of their 30th term is :

⇒ Difference of their 30th term is same as difference of their 1st term.
⇒ Difference of 30th term = Difference of 1st term = 8 – 3 = 5.
