Question

23,48,99,203,413,.......​

Answer 1

Answer:

833

Step-by-step explanation:

In every step, the number is doubled and added by the number of terms before it.

For eg from 23 to 48,

23 is doubled and added with the ntg term +2.

2x+nth term +2

Answer 2

Answer:

837

Step-by-step explanation:

Because in every number after doubling it we have to add it by consequitive prime number we can't add consequitive odd number because as we can see we already added 2 which is a prime and even number,

23*2=46+2=48

48*2=96+3=99

99*2=198+5=203

203*2=406+7=413

413*2=826+11=837

We didn't add 9 here because nine isn't a prime number instead 9 is an odd number.

Hope it will help you
