1.	Check whether the following sequences are G.P. If so write tn. 7, 14, 21, 28,....
Answer» 7, 14, 21, 28,.... t₁ = 7, t₂ = 14, t₃ = 21, t₄ = 28 Here, \(\frac{t_2}{t_1}=2,\frac{t_3}{t_2}=\frac32,\frac{t_4}{t_3}=\frac43\) \(\because\) \(\frac{t_2}{t_1}\neq\frac{t_3}{t_2}\neq\frac{t_4}{t_3},\) the sequence is not a Geometric progression.

Check whether the following sequences are G.P. If so write tn. 7, 14, 21, 28,....

Answer»

7, 14, 21, 28,....

t₁ = 7, t₂ = 14, t₃ = 21, t₄ = 28

Here, \(\frac{t_2}{t_1}=2,\frac{t_3}{t_2}=\frac32,\frac{t_4}{t_3}=\frac43\)

\(\because\) \(\frac{t_2}{t_1}\neq\frac{t_3}{t_2}\neq\frac{t_4}{t_3},\) the sequence is not a Geometric progression.
