Answer 1

Answer: The 31st term is 367

Step-by-step explanation: An arithmetic sequence is derived such that every term is calculated by adding a common difference to the previous term.

The first term has been given as 12. And the value of the nth term shall be defined by the formula

nth term = a(n - 1) + 7. So in order to calculate the unknown term, simply substitute the term for n.

To calculate the 31st term, we apply the formula as follows

nth = a(n - 1) + 7

31st = 12(31 - 1) + 7

31st = 12(30) + 7

31st = 360 + 7

31st = 367

Therefore, the 31st term is 367
