Correct Answer: 57
By using arithmetic progression (AP) series logic formula
a,a+d,a+2d,a+3d,……….
In this question, a =27
d – difference between the first and second number
d= 37- 27=10
We find out the fourth number,
a +3d = 27 + 3(10)
a + 3d = 27+ 30
a + 3d = 57
So 57 is the next term in the series.
