Question

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

Answer 1

10th term = (-137)

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
