Challenge your brain with this sequence riddle.

See the equations and try to find the connection between them and then try to find what comes next in the sequence.

13 + 14 = 65

14 + 15 = 84

15 + 16 = 105

16 + 17 = ???

Answer:

The sequence has the following realtion;

13 + 14 = 13 x (1 + 4) = 13 x 5 = 65;

Similarly;

14 + 15 = 14 x 6 = 84

15 + 16 = 15 x 7 = 105

Therefore;

16 + 17 = 16 x (1 + 7) = 16 x 8 = 128.

Answer = 128
