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
