Answer 1

Step-by-step explanation:

Question 1:

Show that the progression 3, 9, 15, 21,... is an AP. Write down its first term and the common difference.

ANSWER:

The given progression is 3, 9, 15, 21,...

Clearly, (9 - 3) = (15 - 9) = (21 - 15) = 6 (Constant)

Thus, each term differs from its preceding term by 6.

So, the given progression is an AP.

Its first term is 3 and the common difference is 6.

Thus, a = 3, and d = 6
