Question

9,26,77,230 write the series​

Answer 1

Answer:

Given 9,26,77,230 then the next number is 689

Step-by-step explanation:



Given 9, 26,77,230

Let us find the pattern

(9*3)-1= 27-1 = 26

(26*3)-1 = 78-1=77

(77*3)-1=231-1=230

So the next number is

(230*3)-1=690-1 =689

So 9,26,77,230,689
