FIRST DIGIT IS DECIDED BY THE DIFFERENCE OF SUBSEQUENT NUMBERS.AS THE FIRST DIGIT IS 5(OF 52) THE NUMBER IS 52-5=47
THE LAST DIGIT IS DECIDED BY THE SUMMATION OF DIGITS OF SUCCESSOR OF A NUMBER.SO FOR 52,THE NUMBER IS 47 AS 4+7=1+1=2 i.e,THE LAST DIGIT OF 52..

Piyush Telang   9 years AGO

84 - 8 = 76
76 - 7 = 69
69 - 6 = 63
63 - 6 = 57
57 - 5 = 52
52 - 5 = 47
Preceding value is subtracted by its tens digit number to get the following value in the series.
e.g. 84 is subtracted by its tens digit number '8' to get the following value 76 and similarly 76 is subtracted by its tens digit number '7' to get the following value 69 and so on.
So the value after 52 is 47.

Subham Mahanta   9 years AGO

in the following sequence,
first no. is 84 . first no. of 84 is 8. so if we do (84-8), then we get 76
so, similarly,
76-7 = 69
69-6 = 63
63-6 = 57
57-5 = 52
so the next no. of following sequence is
52-5 = 47
ans is option 8

Aarti Galar   9 years AGO

the logic is
whatever be the number at tens place is the no. to be subtracted from the no.
Ex. 84
here, 8 is in tens place so we subtract 8 from 84.
so the answer is 8) 47

each no.can be written as
52=5+2 =7I.e. no carry bit so write it as 57
57=5+7 =12 I.e carry so add 1 to 2 and add 1 to 5 I.e. 63
63=6+3 no carry so 69
69=6+9=15 I.e. add 1 to 5 and add 1 to 6 I.e. 76
76=7+6=13 I.e. add 1 to 3 and 1to 7 I.e. 84
option 8 has answer 47
