Question

missing number1,7,13,19,_,199

Answer 1

This is an Arithmetic Progression.

Numbers are said to be in Arithmetic Progression (A.P.) when the difference between any two consecutive numbers in the progression is constant i.e. in an Arithmetic Progression the numbers increase or decrease by a constant difference.

a, a + d, a + 2d, a + 3d...



7–1 = 6

13–7 = 6

19–13 = 6 … so d is constant.

so next term will be 205.
