10 ,7 ,4 ,1 ,-2 50th term pls help fast

Answer 1

Answer:

10th term = (-137)

Step-by-step explanation:

This is an arithmetic sequence. Each term of this sequence is obtained by subtracting 3 from the previous term.

           n = 50

Common difference = second term - first term

                             d  =  7 - 10

                              d = -3

            a =first term = 10

           $\boxed{\bf T_n = a +(n- 1)*d}$

            $\sf T_{50}=10 + (50 - 1) * (-3)$

                   = 10 + 49 * (-3)

                    = 10 - 147

                    = -137
