1 |
Problem |
Find the general term of the arithmetic progression |
|
2 |
Step |
The given sequence is -1.3,-1.6,-1.9,-2.2… |
|
3 |
Step |
The first term is |
a = -1.3 |
4 |
Step |
The common difference is |
d = -1.6-(-1.3) = -1.6 + 1.3 = -0.3 |
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 = -1.3 + (n-1)(-0.3)\$ |
7 |
Step |
The general term of the given AP is |
\$ a_n = -0.3n - 1\$ |
