Answer:
The next term is 42
Explanation:
Let's use Arithmetic Progression
a₁ = - 3
a₂ = 12
a₃ = 27
Now,
The Formula of Common Difference d is
d = a₂ - a₁
= 12 - (-3)
= 12 + 3
d = 15
d = a₃ - a₂
= 27 - 12
d = 15
Here, the common difference is same
aₙ = aₙ₋₁ + d
a₄ = a₄₋₁ + 15
a₄ = a₃ + 15
a₄ = 27 + 15
a₄ = 42
So, The next term is 42
