Answer:
In the pattern 2,8,26,80... the fourteenth number of the series is multiplied by 3 and two is added to the result to get the fifteenth number
option B
Step-by-step explanation
Given 2, 8, 26, 80....
Let us check the pattern
(2*3)+2 = 8
(8*3)+2= 24+2 = 26
(26*3)+2 =78+2 = 80
So to get any any (n+1) th number, the nth number is multiplied by 3 and 2 is added to it
So, for the fifteenth number,
n +1 = 15
n= 15-1 = 14
So, to get the fifteenth number,
The fourteenth number is multiplied by 3 and 2 is added to the result
so, option B, multiply fourteenth number by 3 and add 2 to the result is the correct answer
