Question

The third term of a sequence is 9. The eighth term of the sequence is 19. Which of these position-to-term rules is correct one for the sequence? show how you worked out your answer
A term = position number +9
B term = 3× position number
C term = 2× position number +3
D term = 4× position number -3​

Answer 1

Answer:

C term

Step-by-step explanation:

If we take,

A term-

position no. = 3,8

3 + 9 = 12

8 + 9 = 17

Hence, it is wrong

B term -

position no. = 3,8

3×3=9

3×8=16

Hence, it is wrong

C term -

position no. = 3,8

2×3+3=9

2×8+3=19

Hence, it is correct

D term -

position no. = 3,8

4×3-3=9

4×8-3=29

Hence, it is wrong
