Answer 1

156 is the wrong number

Answer 2

Answer:

Heya mate your answer there

Step-by-step explanation:

Given sequence 146 , 74 , 40 , 23 , 19.5 , 18.75

now 146/2 + 1=74

74/2 + 3 = 40

40/2 + 5 (here according to question it adds 3 viz. incorrect) = 25 (correct value)

let check for further values

25/2 + 7 = 19.5

19.5/2 + 9 = 18.75

So number 23 doesnot belong to the sequence.
