Question

In the given number series , write the next four numbers.
3/4, 3/2, 9/4 ,3, __ , __ , __ , __

Answer 1

a¹ = 3/4 , d= 3/2-3/4 = 3/4
a5= a + (n-1) *d
= 3/4 +(5-1)*3/4
=3/4 + (4*3/4)
=3/4 + 12/4 = 15/4

a6= 3/4 +(6-1) *3/4
=3/4 +(5*3/4) = 3/4+(15/4)
=3/4+15/4 =18/4
=9/2

a7= 3/4 +(7-1)*3/4 = 3/4+(6*3/4)
= 3/4+18/4 = 21/4

a8= 3/4 +(8-1) *3/4 = 3/4 +(7*3/4)
= 3/4+21/4 = 24/4
=6

Answer--The next 4 nos. are - 15/4, 9/2 , 21/4 , 6
