Question

number series of 1,3,9,23,53,115,241​

Answer 1

Answer:

Step-by-step explanation:

This is a three tier series.

1 - 3= 2. Like 2-6=4.

3 - 9= 6. 6-14=8. 4×2=8

9 - 23= 14. 14-30=16. 8×2=16

23 - 53= 30. 30-62=32. 16×2=32

53 - 115= 62. 62-126=64. 32×2=64

115 - 241= 126. So,64×2=128. Then add both 128+126=254 final add 254+241=495 so answer is 495
