1) 6 2) 5 3) 8 4) 9 .
with explanation please. ​

Answer 1

Given: 12234345645678 a b c d e

To find: The value of b

Solution: The given series follows a pattern.

For the first iteration, i.e., for the first number (1), two consecutive numbers are generated (12).

For the second iteration, for the second number (2), three consecutive numbers are generated (234).

For the third iteration, i.e., for the third number (3), four consecutive numbers are generated (3456).

For the fourth iteration, i.e., for the fourth number (4), five consecutive numbers are generated (45678).

Hence following the same pattern, for the fifth iteration, i.e., for the fifth number (5), six consecutive numbers should be generated (5678910).

So we get, a=5, b=6, c=7, d=8 and e=9.

Answer: The value of b is option 1) 6.
