The above series follows the following pattern-
23
23 × 1 – 1 = 22
22 × 1.5 – 1 = 32
32 × 2 – 1 = 63
63 × 2.5 – 1 = 156.5
156.5 × 3 – 1 = 468.5
Hence, the missing number is 156.5.
23
23 × 1 – 1 = 22
22 × 1.5 – 1 = 32
32 × 2 – 1 = 63
63 × 2.5 – 1 = 156.5
156.5 × 3 – 1 = 468.5
Hence, the missing number is 156.5.
