What is the 50th term of this sequence? Round to the nearest thousandth (if necessary) 261, 256, 251.

'n' stands for the term number so to find the 50th term we would just substitute 50 in the formula in place of 'n'.

nth term = dn + (a - d)

This time there is a letter c which stands for the second difference (or the difference between the differences and d is just the difference between the first two numbers.

Step-by-step explanation:

261 rounded to nearest thousandth is 1,000  and 256 is 1,000 and 251 is 1,000 so your answer is 3,000.

i'm assuming it's looking for the missing length, which should be 4cm
