Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Write the next three terms of the given geometric progression : 1,4,16,… |
|
2 |
Step |
The given geometric series is 1,4,16,… |
|
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) = 4/1 = 4\$ |
5 |
Step |
The next number after 16 is obtained by multiplying 16 with the common ratio (r=4) |
\$ 16 \times 4 = 64 \$ |
6 |
Step |
The next number after 64 is obtained by multiplying 64 with the common ratio (r=4) |
\$ 64 \times 4 = 256 \$ |
7 |
Step |
The next number after 256 is obtained by multiplying 256 with the common ratio (r=4) |
\$ 256 \times 4 = 1024 \$ |
8 |
Step |
The next three terms of the given geometric series are 64,256,1024 |
