(a) 3

(d) 63 please explain it​

Answer 1

Hi this is your answer -

Starting with the first number ‘1’, we move ahead in the way given below:

1 x 2 + 1 = 3

3 x 2 + 1 = 7

7 x 2 + 1 = 15

15 x 2 + 1 = 31

31 x 2 + 1 = 63

63 x 2 + 1 = 127

Therefore 127 is the next number in the series.

Answer 2

Answer:

C is incorrect.

Because all are the multiple of two.

1+2=3

3+4=7

7+8=15

8+11=26 (but here 8+16=24)

Hence, this reason 26 is wrong...
