Question

Find AP whose nth term is 3n-5

Answer 1

Hey mate!!

Here's your answer...

Given,

nth term = 3n - 5

 First term = a1 = 3(1) - 5 = -2

Second term = a2 = 3(2) - 5 = 1

Third term = a3 = 3(3) - 5 = 4

 Thus, the AP is

-2, 1, 4,....

Answer 2

Mark as the brainliest.

Step-by-step explanation:

Given, a = 3n-5

Putting n= 1, 2, 3, 4, ... in (i), we get

- 3 x 1-5-3-5--2, a₂ = 32-5-6-5 = 1, 4-3x3-5-9-5-4, a = 3 x 4 - 5 = 12 - 5 = 7, ...

Hence, the A.P. is -2, 1, 4, 7, ...
