Answer:

Option (3)

Step-by-step explanation:

For a geometric progression,

$a,ar,ar^{2},ar^3.........a(r)^{n-1},a(r)^n$

First term of the progression = a

Common ratio of each successive term to the previous term = r

Recursive formula for geometric progression will be,

$a_1=a$

And $a_{n}=a_{n-1}(r)$

Following this rule for the G.P. given in the question,

$a_1=4$

$a_n=-1.5a_{n-1}$

Therefore, from the recursive formula,

Common ration 'r' = -(1.5)

Option (3) will be the correct option.

Harry received a package for his birthday. The package weighed 350,000 centigrams. Select the conversions that are equivalent to

notsponge [240]

Given:

The package weighed 350,000 centigrams.

To find:

The conversions that are equivalent to 350,000 centigrams

Solution:

We know that,

1 centigrams (cg) = 0.000001 kilograms (kg)

1 cg = 0.1 decigrams (dg)

1 cg = 0.001 dekagrams (dag)

1 cg = 0.01 grams (g)

Using these conversions, we get

350,000 centigrams = 3.5 kilograms

350,000 centigrams = 35,000 decigrams

350,000 centigrams = 350 dekagrams

350,000 centigrams = 3,500 grams

Therefore the correct options are C and D.
