how about 92?

Log in to reply

631 is the answer......

17*2=34 then we'll reverse it we got.....43

now....43*2= 86...... reverse it we'll get....68

now....68*2=136 reverse it we'll get 631....

however....92 is correct...too....since the difference b/w consecutive digits....are in decreasing order...i.e.25,24,23...... but ....take...product rule... in consideration mostly....

You need more terms to no for sure but it looks like an arithmetic progression of the second order, in which case it will be 92.

You could be adding squares of 16, 25, then 36 to get 114

Or 172.

how 172?

17 times 4 is 68. So 4 times 43 is 172.
