What is the next number of the following sequence
84, 90, 94.5, 103.5,........

OPtion

1) 114.5
2) 107.5
3) 118.5
4) 118
5) 108
6) 120
7) 108.5
8) 112.5
9) 112
10)None of these

Solution

84
84 + 6 = 90 (number(84) + sum of all digit/2)
90 + 4.5 = 94.5 (----------)
94.5 + 9 = 103.5 (--------)
Similarly
103.5 + 4.5 = 108 (--------)

Option 5)

Correct Option: 5 Best Solution (24)

ROHIT KUMAR DUBEY   9 years AGO

84=(8+4)/2=6
84+6=90
(9+0)/2=4.5
90+4.5=94.5
(9+4+5)/2=9
94.5+9=103.5

Yadu Vir Singh   9 years AGO

84 + (8 + 4)/2 = 90
90 + (9 + 0)/2 = 94.5
94.5 + (9 + 4 + 5)/2 = 103.5
103.5 +(1 + 0 +3 + 5)/2 = 108 Ans.

add both the digits of the number and divide it by 2 and then add the result to the next term

Like? Yes (2) | No   

Vivek Ratan   9 years AGO

after adding the previous no's digits and making half of them, when we add the resultant with the previous no we get next no.

NAVEEN KUMAR   9 years AGO

84, 84+(8+4)/2=90,90+(9+0)/2=94.5,94.5+(9+4+5)/2=103.5
similarly ,
next term=103.5+(1+0+3+5)/2=108

Shreeya Kharbanda   9 years AGO

The first term in series is 84
To calculate the next term, firstly we calculate the sum of digits and then divide it by 2
So, 8+4=12 and 12/2=6
Then we increment 84 by 6, so we get the next term which is 90
Similarly we proceed to calculate the third term as follows
9+0=9 and 9/2=4.5
90+4.5=94.5
And for the fourth term
9+4+5=18 and 18/2=9
94.5+9=103.5
And similarly we calculate the fifth term
1+3+5=9 and 9/2=4.5
103.5+4.5=108

ans -108
difference is 6 in first and second 4.5 and third 9...
so now 4.5 add to 103.5

Yallapu Uday tarun kumar   9 years AGO

sum should be 9 (Option 5 and 8 has sum 9)
Most probably next number should be a integer so opted for option 5

luciya   9 years AGO

8+4=12/2=6
84+6=90
9+0=9/2=4.5
90+4.5=94.5
9+4+5=18/2=9
94.5+9=103.5
1+0+3+5=9/2=4.5

103.5+4.5= 108

Dinni   9 years AGO

add the digits and divide by 2
103.5 = 9/2=4.5
103.5+4.5=108

Like? Yes (1) | No   

mish mehta   9 years AGO

84:(8+4)/2=6 now,84+6=90
90:(9+0)/2=4.5 now 90+4.5=94.5
94.5(9+4+5)/2=9 now 94.5+9=103.5
similarly,
103.5:(1+0+3+5)/2=4.5 now 103.5+4.5=108.
hence the next no. will be 108

RAHUL AGARWAL   9 years AGO

pattern ( to get next term = previous term + add all the digits of previous term & divide by 2)
84+(8+4)/2=84+6=90
90+(9+0)/2=90+4.5=94.5
94.5+(9+4+5)/2=103.5
103.5+(1+3+5)/2=108

add digits n divide it by 2 n add the result to base ans.
84-> (8+4)/2=6 => 84+6=90
90-> (9+0)/2=4.5 => 90+4.5=94.5
94.5-> (9+4+5)/2=9 => 94.5+9=103.5
103.5-> (1+0+3+5)/2=4.5 => 103.5+4.5=108

Saleel Kulkarni   9 years AGO

Logic is addition of the given number and the half of sum of all the digits in the number is the next number.

84+((8+4)/2)=90
90+((9+4)/2)=94.5
94.5+((9+4+5)/2)=103.5
103.5+((1+0+3+5)/2)=108

Arti saraswat    9 years AGO

(8+4)/2=6 then 6+84=90.
Again,
(9+0)/2=4.5 then 4.5+90=94.5.
Similarly
(9+4+5)/2=9 then 9+94.5=103.5.
Similarly
(1+0+3+5)/2 then 4.5+103.5=108
