Q. 1 A4.6( 36 Votes )

# Show that each of the progressions given below is an AP. Find the first term, common difference and next term of each.9, 15, 21, 27, ...

Here, T2 - T1 = 15 - 9 = 6

T3 - T2 = 21 - 15 = 6

T4 - T3 = 27 - 21 = 6

Since the difference between each consecutive term is same, the progression is an AP.

So, first term = 9

Common difference = 15 - 9 = 6

Next term = T5 = T4 + d = 27 + 6 = 33
