Question

The 10th term of ap exceed f5th term by how much if common difference is 3/2

Answer 1

Answer:

7.5

Step-by-step explanation:

let 1st term = a

common difference = d = 3/2

nth term = a+(n-1)d

10th term = a+(10-1)×3/2 = a+27/2

5th term = a+(5-1)×3/2 = a+12/2

10th term - 5th term = (a+27/2) - (a+12/2) = a+27/2 - a-12/2 = 15/2 = 7.5

Answer 2

Answer:

7.5

Step-by-step explanation:

let 1st term = a

common difference = d = 3/2

nth term = a+(n-1)d

10th term = a+(10-1)×3/2 = a+27/2

5th term = a+(5-1)×3/2 = a+12/2

10th term - 5th term = (a+27/2) - (a+12/2) = a+27/2 - a-12/2 = 15/2 = 7.5
