The number of red beads are increasing by 2 for each new pattern
The next number of reds will be 12. ( in patern 5)

number of blue beads in pattern 5 will be 15 ( increasing by 3 )

nth term for red = 4 + 2 (n-1) ( its an arithmetic sequence)

nth term for blue = 3 + 3(n - 1) - as above ,arithmetic.

Total beads in pattern 45 is

No. red beads in pattern 26 = 4 + 2(26-1) = 4 + 50 = 54
No blue beads in pattern 60 = 3 + 3(59) = 180

Total number of beads in pattern 45 is:-

4 + 2(44) + 3 + 3(44) = 227
