Answer 1

Answer:

16,12,18,60,80,212,260

Answer 2

The missing number in the series 16,12,18,?,80,212 is 35.

the series is following the order of:

let the series be A,B,C,D,E,F

B = A* X + Y

where, X = 0.5 and increments 0.5  subsequently

where Y = 4 and increments 2  subsequently

so we have,

A* X + Y     = B

16 * 0.5 + 4 =12

12 * 1     + 6 = 18

18  * 1.5 + 8 = 35

35* 2     + 10 = 80

80 * 2.5 + 12 = 212

Hence, The missing number in the series 16,12,18,?,80,212 is 35.
