Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the general term of the arithmetic progression |
|
2 |
Step |
The given sequence is \$5\sqrt3,\sqrt3,-3\sqrt3,-7\sqrt3,-11\sqrt3,...\$ |
|
3 |
Step |
The first term is |
\$a = 5\sqrt3\$ |
4 |
Step |
The common difference is |
\$d = \sqrt3 - 5\sqrt3 = - 4\sqrt3\$ |
5 |
Formula: |
The general term of an AP is calculated by the formula |
\$ a_n = a + (n-1)d\$ |
6 |
Hint |
Substitute a,d values in formula |
\$ a_n = (5\sqrt3) + (n-1)(- 4\sqrt3)\$ |
7 |
Step |
The general term of the given AP is |
\$ a_n = - 4\sqrt3n + 9\sqrt3\$ |
