Answer 1

Answer:

Step-by-step explanation:

1) let the first term in GP = a

a= 50 (given ) ---(1)

general form of nth term in GP = an = a r^n-1

a4 = 1350

ar³ =1350

⇒50*r³ = 1350 [from (1)]

⇒ r³ = 1350/50

⇒r³ = 27

⇒r³ = 3³

∴r=3

now 

fifth term in Gp = a5 = ar^4 = 50 * (3) ^4 = 50 *81 = 4050
