Question 6 of 20

Answer 1

Answer:

C.  -4

Step-by-step explanation:

Given sequence:  51, 47, 43, 39, ...

To find the common difference (d) between consecutive terms in an arithmetic sequence, subtract the previous term from the next term:

$\implies \sf d=47-51=-4$

$\implies \sf d=43-47=-4$

$\implies \sf d=39-43=-4$

Therefore, the common difference for the given arithmetic sequence is -4.

Answer 2

Common difference formula

$\boxed{\sf d=t_2-t_1}$

So

Here

$\\ \tt{:}\longrightarrow d=47-51$

$\\ \tt{:}\longrightarrow d=-4$
