Answer:
The least value of n is 17.
Step-by-step explanation:
First term (a) = 46
Second term (a + d) = 43
Third term (a + 2d) = 40
Common difference (d) = second term - first term = 43 - 46 = -3
Tn (nth term) = a + (n - 1)d
a = 46, d = -3
Tn = 46 + (n - 1)-3 = 46 + (-3n + 3) = 46 - 3n + 3 = 49 - 3n
For Tn to be negative, the product of 3 and n must be greater than 49.
Therefore, the least value of n is 17
