KRISHNA CHANDRA UPADHYAY 10 years AGO

THE DIFFERENCE BETWEEN TWO CONSECUTIVE NUMBERS OF THE GIVEN SERIES IS EQUAL TO THE PRODUCT OF DIGITS OF A NUMBER PLUS 1........i.e
93-57=36 i.e 7*5+1=36
121-93=28 i.e 9*3+1=28
124-121=3 i.e 1*2*1+1=3
133-124=9 i.e 1*2*4+1=9
now, suppose the next number is X
then,
X-133=1*3*3+1
X-133=10
therefore,
X=143
hence, the next no. of the given series is 143.
HENCE, OPTION (7) IS CORRECT.

for 57 the next number is 57+(5*7)+1
for 93 the next number is 93+(9*3)+1
for 121 the next number is 121+(1*2*1)+1
for 124 the next number is 124+(1*2*4)+1
similarly for 133 the next number is 133+(1*3*3)+1=143

ABHINAV THAKUR 10 years AGO

The given series is 57, 93,121,124,133,.....
If we find the product of digits of 57, it will be 35, If we add 1 to it we get the next term, i.e., 57+35+1=93, Similarly, 93+27+1=121,
121+2+1=124,
124+8+1=133. Hence, next term will be 133+9+1=143.

BHANU KUMAR 10 years AGO

57 93 121 124 133
we can think it as...........
57=5*7+1=36
so next no is 57+36=93
9*3=27+1=28
so next no is 93+28=121
1*2*1=2+1=3
so next no is 121+3=124
1*2*4=8+1=9
so next no is 124+9=133
1*3*3=9+1=10
so next no is 133+10=143 (OPTION 7)

Rohan 10 years AGO

multiply the digits of the number and add 1 to it and then add the obtained number to the initial number.

i.e
57 = (5*7)+1 = 36
57 + 36 = 93

93= (9*3)+1 = 28
93+28 = 121

similarly
133 = (1*3*3)+1 = 10
133+10 = 143

therefore 143 is the next number of the series

The logic is

57+(5×7)+1=93
93+(9×3)+1=121
121+(2×1)+1=124
124+(2×4)+1=133

DIPAK TIWARI 10 years AGO

Logic is that difference between A number from its next one and multiplication of A number and there difference is 1
93-57=36 and 5*7=35
Now 36-35=1
Similarly 121-93=28 and 9*3=27
Now 28-27=1
Again 124-121=3 and 1*2*1=2
Now 2-1=1
Again 133-124=9 and 1*2*4=8
Now difference 9-8=1
143-133=10 and 1*3*3=9
Hence difference 10-9=1
So 143 is correct

93=9*3=27 and +1=>28--------->2nd diff
121=1*2*1=2 and +1=>3-------->3rd diff
124=1*2*4=8 and +1=>9-------->4th diff
