The next term of the series in the problem is 10
EXPLANATION:
Adding the square of the tens digit with the units digit of a given term of the sequence gives the succeeding term of the sequence.
Thus, we observe that:
97 = 97
9^2 + 7 = 88
8^2 +8 = 72
7^2 + 2 = 51
5^2 + 1 = 26
2^2 + 6 = 10
Consequently, the next term of the series in the problem is 10.

Previous day Question
What is the next number of this serious . 98 88 72 51 26 ....?
Can you see the difference between the questions?
In my poinion, you are misusing the good facilities granted by " YAHOO ".
Anyway Pl. don't repeat this sort of things.

-3
The differences between 97, 88, 72, 51, 26 are 9, 16, 21, 25 (First Differential);
The differences between 9, 16, 21, 25 are 7, 5, 4 (Second Differential);
The differences between 7, 5, 4 are 2, 1, respectively (Third Differential).
Thus the next level should be 0 in Third Differential, thus giving 4 in Second Differential, thus giving 29 in First Differential, thus giving (-3, i.e., 26 - 29 = -3)
