In a G.P. the third term is 24, and the sixth term is 192. Find the tenth term.​


{ \boxed{ \red{ \bold{3072}}}}

Step-by-step explanation:

Given,

{ \green{ \sf{ {ar}^{2}  = 24}}} \: { \to} \: { \tt{ {eq}^{n} (1)}}

{ \green{ \sf{ {ar}^{5}  = 192}}} \: { \to} \: { \tt{ {eq}^{n} (2)}}

From Eqⁿ (2),

{ \green{ \sf{ {ar}^{2}. {r}^{3}  = 192}}}

{ \green{ \sf{24. {r}^{3}  = 192}}}

{ \green{ \sf{ {r}^{3}  =  \frac{192}{24}}}}

{ \green{ \sf{ {r}^{3}  = 8}}}

{ \green{ \sf{ {r}^{3}  =  {2}^{3}}}}

{ \boxed{ \purple{ \sf{r = 2}}}}

From Eqⁿ (1)

{ \blue{ \sf{ {ar}^{2}  = 24}}}

{ \blue{ \sf{a {(2)}^{2}  = 24}}}

{ \blue{ \sf{4a = 24}}}

{ \blue{ \sf{a =  \frac{24}{4}}}}

{ \boxed{ \purple{ \sf{a = 6}}}}

10th term is,

{ \orange{ \sf{ {ar}^{9} }}}

{ \orange{ \sf{6 {(2)}^{9}}}}

{ \orange{ \sf{6(512)}}}

{ \bold{ = }}{ \boxed{ \red{ \bold{3072}}}}
