What will come in place of the question mark (?) in the following number series?
55, 66.15, 88.45, 121.9, 166.5, ?
Successive multiples of 11.15 are added.
55 $$+ (11.15 \times 1)$$ = 66.15
66.15 $$+ (11.15 \times 2)$$ = 88.45
88.45 $$+ (11.15 \times 3)$$ = 121.9
121.9 $$+ (11.15 \times 4)$$ = 166.5
166.5 $$+ (11.15 \times 5)$$ = 222.25
