Q. 1 B4.4( 15 Votes )

# Show that each of the progressions given below is an AP. Find the first term, common difference and next term of each.11, 6, 1, - 4, ...

Here, T2 - T1 = 6 - 11 = - 5

T3 - T2 = 1 - 6 = - 5

T4 - T3 = - 4 - 1 = - 5

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

So, first term = 11

Common difference = 6 - 11 = - 5

Next term = T5 = T4 + d = - 4 + (-5) = - 9
