Answer:
-4
Step-by-step explanation:
Take the second term and subtract the first term
50 -54 = -4
We can check by taking the third term and subtracting the second term
46-50 = -4
The common difference is -4
If we will analyze, we will notice a standard:
- From 54 to 50 we subtracted 4 --> (-4);
- From 50 to 46 we subtracted 4 --> (-4);
This is repeated until last term of sequence.
