Question

What is the answer of 6th question
Please write with solution

Answer 1

Answer is option a. 4n-13

4(1) -13 = 4-13=9

4(2)-13 = 8-13=5

4(3)-13 = 12-13 =1

4(4)-13 = 16-13 = -3

4(5)-13 = 20-13 =-7

Answer 2

Answer:

6) c. 13-4n

13-4(1)= 13-4= 9

13-4(2)=13-8= 5

13-4(3)=13-12 = 1

13-4(4) = -4

and so on

7. 24-3n = 24-3(1)= 24-3= 21

24-3(2)=24-6=18.

let nth term = -81.

A/Q

24-3n = 81

so, -3n = -105

so, n = -105 ÷ (-3) = 35.

So, -81 is the 35th term of that series
