Another Geometry Puzzle Pattern!?

Question

18,46,94,63,52,61, ? Whats after 61?

& how did you get answer?

Answer 1

each number is the reverse of a perfect square

18->81 which is 9^2

46->64 which is 8^2

61->16=4^3

so the next number is 90, which gives you 09 or 9 which is 3^2

I suppose you can argue whether the next number should be 90 or 9, but the pattern is described

Answer 2

Look at those numbers reversed - we have...

81,64,49,36,25,16

We get 81 from 9x9

64 from 8x8

49 from 7x7

See the pattern now?

36 from 6x6

25 from 5x5

16 from 4x4

to get the last number ...3x3= 9
