what is the next number of this serious . 98 88 72 51 26 ....?

Answer 1

MINUS 2

Answer 2

98 88 72 51 26 54 98-88=10 88-72=16 72-51=21 51-26=25

Answer 3

it should be a 3 cos when you're counting 98 88 72 51 26/
10 16 21 25/
6 5 4 3 you can't skip from 4 to 2 you have to go through 3- although if you add it correctly the number following 25 has to be 2

Answer 4

The answer will be -2.
Reason :
98 88 72 51 26
Diff. of the first series 10 16 21 25
Diff. of the second series 6 5 4
Diff. of the third series 1 1

Therefore the next term of the third series will be 1;
i.e. the next term of the second series will be 4-1=3;
i.e. the next term of the first series will be 25+3=28;
Therefore the next term of the given series : 26-28=-2

Answer 5

1

Answer 6

98 - 88 = 10
88 - 72 = 16
72 - 52 = 21
52 - 26 = 25

now, here the difference between 10 and 16 is 6
the difference between 16 and 21 is 5
the difference between 21 and 25 is 4

so the next difference must be 3

so, 25 + 3 = 28

so 26 - 28 = -2

therefore next term in this series is -2.

Answer 7

98-88 =10
88-72= 16
72-51=21
51-26=25

The difference between the difference of 2 successive numbers is 6,5,4 ... so the next numbers will be 26-(25+3) = 26-28 = -2.

Answer 8

The difference between the numbers is 10 16 21 25.
These numbers have a difference of 6 5 4 and the next difference will be 3
so the difference of the original serie will be 28.
26-28 = -2

This answer has already been given, but trying to get the answer a little more precise.

Answer 9

4.

98 - 88 = 10
88 - 72 = 16
72 - 51 = 21
51 - 26 = 25
26 - X = Y

10-16 = -6
16-21 = -5
21-25 = -4
Y - 25 = -3

Y = 22

26 - X = 22

X = 4

Answer 10

it is -2

Answer 11

28
