​

Answer 1

Answer:

Just find the common difference...and put in a n formula....and you get your result...

Hope it helps....

Answer 2

Answer:

24

Step-by-step explanation:

equating the common difference :

3x - (x+1) = 4x +2 - 3x

or, 2x - 1 = x +2

or, x = 3

∴ 1st term = x + 1 = 4

  2nd term = 3 x 3 = 9

∴ common difference = 9-4 =5

5th term = 4 + (5-1)* 5 = 24       [∵nth term = a + (n-1)d]
