Q14 of 110 Page 65

The sequence –3, –3, –3,… is

The given sequence is -3, -3, -3


Test for AP


If a,b,c…are in AP the b-a = c-b…


-3-(-3) = -3-(-3) = 0


Therefore, the series is in AP.


Test for GP


If a,b,c.. are in GP then …



Therefore, the series is in GP.


The series is both in AP and GP.


So the correct option is D.
