1 |
Problem |
Write the next four terms of the given geometric progression : 2,6,18,… |
|
2 |
Step |
The given geometric series is 2,6,18,… |
|
3 |
Step |
We know that geometric progression is a series of numbers in which each term is obtained by multiplying the previous term by a fixed number, known as the common ratio. |
|
4 |
Formula: |
common ratio of the given geometric series is given by |
\$ r = (r_2)/(r_1) = 6/2 = 3\$ |
5 |
Step |
The next number after 18 is obtained by multiplying 18 with the common ratio (r=3) |
\$ 18 \times 3 = 54 \$ |
6 |
Step |
The next number after 54 is obtained by multiplying 54 with the common ratio (r=3) |
\$ 54 \times 3 = 162 \$ |
7 |
Step |
The next number after 162 is obtained by multiplying 162 with the common ratio (r=3) |
\$ 162 \times 3 = 486 \$ |
8 |
Step |
The next number after 486 is obtained by multiplying 486 with the common ratio (r=3) |
\$ 486 \times 3 = 1458 \$ |
9 |
Step |
The next four terms of the given geometric series are 54,162,486,1458 |
