9, 46, 23, A, 58, 29, 146, B, 366, C, 916...

Find A, B and C.

A between 23 & 58, B between 146 and 366 and C between 366 & 916

A=116, B=73, C=183

multiply 1st number by 5 and add 1, then halve, multipy 3rd number by 5 and add 1, then halve and have again, multipy the 6th number by 5 and add 1, then halve, multipy the 8th number by 5 and add 1, then halve, multipy the 10th number by 5 and add 1.

I think
