In an arithmetic sequence of numbers that has a1 = -4 and a = 46, the value of the 12th number is mathematically given as
T 12 = 106, Option D is correct
What is the value of 12th number?
Generally, the equation for the arithmetic sequence is mathematically given as
Tn = a + (n-1)d
Where
a1 = -4
and
T6 = a6 = 46
T6= -4 + 5d
50 = 5d
d = 10
In conclusion
T12 = -4 + (12-1)10
T12= -4 +110
T 12 = 106
