Question

Let a, b, c be the three rational numbers where a

3

4

 , b

–4

5

 and c

2

3​

Answer 1

It’s 3,4,b,-4,5,c,2,3

Here ,

R4 and R5=x= R6

-4 +5=1 =R6

Then

R1+R2 =R3
3+4=7

So b = 1
And c = 7

It’s actually Fibonacci Series which is defined as n2 = n1+^- n3 , which means second term is based on 1st and 3rd term

I hope it will help you

Thank you
