(Show Source): You have the right to put this equipment on her website! succession is 10, 6,2,-2,-6. I have to discover the nth term, the 12th term and also 27th term.Step 1. Look for a pattern. Difference between 10 and 6 is 4. The distinction of 6 and also 2 is additionally 4. Difference between 2 and also -2 is likewise four, and the difference between -2 and -6 is four. Step 2. So very first term is 10 need to subtract 4 to obtain 6. 10 - 4(n-1) whereby n=2 for 6. Action 3. Check out if the formula works for the rest of the sequence. 10-4(n-1)= 10-4n-1=11-4n (as we point out in action 1, the distinction is 4. Now we recognize the an initial term is 10 so once n is 1 we acquire 10 due to the fact that 10-4(1-1)=10. Once n is 2, we gain 6 due to the fact that 10-4(2-1)=6. Once n is 3, we obtain 10-4*(3-1)=-2. For n=4, we get 10-4*(4-1)=-6. Therefore the formula works. Action 4. ANSWER: The equation for the sequence is 10-4(n-1) or 11-4nStep 5. ANSWER. Because that n=12, climate 11-4n=11-4*12=-37Step 5.
