1 |
Problem |
Find the 17th term for the given AP: 5, 10, 15, 20, …. |
|
2 |
Step |
Given AP: 5, 10, 15, 20, …. |
|
3 |
Clue |
Given |
\$ a = 5, n = 17\$ |
4 |
Formula: |
Common difference |
\$ d = a_2 - a_1 = 10 - 5 = 5\$ |
5 |
Formula: |
The Arithmetic Progression formula |
\$ a_n = a + (n-1)d\$ |
6 |
Hint |
Substitute \$a,d,n\$ values in formula |
\$ a_17 = 5 + (17 - 1)5\$ |
7 |
Step |
After simplification we get |
\$ a_17 = 5 + 16 \times 5\$ |
8 |
Step |
After simplification we get |
\$ a_17 = 5 + 80\$ |
9 |
Step |
After simplification we get |
\$ a_17 = 85\$ |
