Question

20,30,60,150,450 find next series​

Answer 1

Answer:

1575

Step-by-step explanation:

20

20*1.5=30

30*2=60

60*2.5=150

150*3=450

450*3.5=1575

Answer 2

Given expressions are $20,30,60,150,450$

The difference between the first two terms is

$30-20\\=10$

This difference we can rewrite like $20 \times 1.5= 30$

We got the second term.

The difference between the second and third terms is

$60-30\\=30$

This difference we can rewrite like $30 \times 2= 60$

We got the third term

The difference between the third and fourth terms is

$150-60\\=90$

This difference we can rewrite like $60 \times 2.5= 150$

We got the fourth term.

The difference between the fourth and fifth terms is

$450-150\\=300$

This difference we can rewrite like $150 \times 3= 450$

We got the fifth term.

Therefore, the general term of change is $1+0.5n$, where n is the number of terms.

The sixth term is $450 \times 3.5=1575$

Therefore, the required term is 1575.
