Question

find AP. (1)An= 3n+2,(2)An=n-1/3.​

Answer 1

Answer:

Step-by-step explanation:

1) An = 3n + 2

n =1, A1 = 3×1+2 = 5

A2 = 3×2 +2 = 8

A3 = 3×3 + 2 = 11

A4 = 3 ×4 + 2 =14

So the AP is

5,8,11,14...

2) An = n -1/3

n =1, A1 = 1-1/3 = 0

n =2, A2 = 2-1/3 = 1/3

n = 3 A3 = 3 -1/3 = 2/3

n =4 A4 =4-1/3 = 1

So the AP is

0, 1/3, 2/3, 1 ....
