Answer:

The sequence is of the form

9 , 13 , 17 , 21 , 25 ,29

Explanation:

Explanation:-

Step(i):-

Given sequence , ___, __17_ ,___,___ 29

The third term = 17

a + (3-1)d = 17

a + 2 d = 17 ...(i)

The sixth term = 29

a + (6-1)d =29

a + 5 d = 29 ...(ii)

solving (i) and (ii) equations

Subtracting (i) and (ii) equations , we get

a + 2 d -a -5 d = 17 -29

- 3 d = - 12

d =4

Substitute 'd' =4 in equation (i)

a + 2 d = 17

a + 2(4) =17

a = 17 -8 = 9

Step(ii):-

The arithmetic sequence

a , a+d , a+2 d , a+ 3 d , a+ 4 d , a+5 d

9 , 9 + 4, 9 +2 (4) , 9+3(4) , 9 +4(4) , 9+5(4)

9 , 13 , 17 , 21 , 25 ,29

Conclusion:-

The sequence is of the form

9 , 13 , 17 , 21 , 25 ,29
