Question

Two ap.s have the same cimmon difference the first term of one of these is 3 and that of the other is 8 what is the difference between their 10th terms

Answer 1

Answer:

5

Step-by-step explanation:

first term of first AP = a = 3

common difference = d

nth term = a + (n-1)d

10th term = 3 + (10 - 1)d

= 3 + 9d

first term of 2nd AP = a = 8

common difference = d

10th term = 8 + (10-1)d

= 8 + 9d

difference between their 10th terms

8 + 9d - (3 + 9d)

= 8 + 9d - 3 - 9d

= 8 - 3 (as common difference of both AP is same)

= 5

hope you get your answer
