Shubhankar Datta  (9 years ago)

first take only one number 1
1*7=7
7+1=8
then series consists of 3 number 1 7 8
then 7*7=49
8*7=56
56+1=57
mow the series become 1 7 8 49 56 57
next
49*7=343
56*7=392
57*7=399
399+1=400
SO ans=392

ANS : 3192
1,7,8,49,56,57,343....??
1,7^1,8,7^2,7*8,(7*8)+1(add number before 7),7^3,... so next will be 56*57 and after that (56*57)+49(add number before 56) and after that 7^4

So it will 1,7,8,49,56,57,343,56*57,(56*57)+49,7^4,....

so according to question next to 343 is 56*57 = 3192

NIRBHAY KUMAR  (9 years ago)

First take 1 and 7

1+7=8
then 2nd term of addition

7*7=49
then result of addition
8*7=56
when we take First two 1 n 7 we find next 3 terms

again we take next two 8 and 49

same process
8+49=57

49*7=343

57*7=399

so series will be.........

1 , 7 , 8 , 49 , 56, 57, 343, 399

Is this solution Helpfull? Yes | No (1)
