Which of the numbers doesnot belong in the number series 1 – 2 – 5 – 10 – 13 – 26 – 29 – 48

is it

a. 1
b. 5
c.26
D.27
E. 48

the sequence first numbe * 2, +3, *2

so 48 doesnot belong it should be 58

Step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

an altitude of 15,000 feet
