|
2 |
Step |
Given AP: 2, 5, 8, 11, …. |
|
3 |
Clue |
Given |
\$ a = 2, n = 20\$ |
4 |
Formula: |
Common difference |
\$ d = a_2 - a_1 = 5 - 2 = 3\$ |
5 |
Formula: |
The Arithmetic Progression formula |
\$ a_n = a + (n-1)d\$ |
6 |
Hint |
Substitute \$a,d,n\$ values in formula |
\$ a_20 = 2 + (20 - 1)3\$ |
7 |
Step |
After simplification we get |
\$ a_20 = 2 + 19 \times 3\$ |
8 |
Step |
After simplification we get |
\$ a_20 = 2 + 57\$ |
9 |
Step |
After simplification we get |
