Answer:
52
Step-by-step explanation:
The general arithmetic sequence formula for this case is
a(n) = -4 + d(n - 1).
Thus, a(15) = -4 + 4(14) = 52
Answer:
The 15th term = 52
Step-by-step explanation:
a₁ = -4
d = 4
n = 15
a₁₅ = The value of the 15th term, (this is what we have to find out)
We know that formula of an arithmetic series is:
aₙ = a₁ + d(n - 1)
Now we can substitute the given values in:
a₁₅ = -4 + 4(15 - 1)
a₁₅ = -4 + 4(14)
a₁₅ = -4 + 56
a₁₅ = 52
So the 15th term = 52
Hope this helps!
