:
a + 1 = multiple of 11, and a is prime, that's easy to find
a = 43, ( 44 in 1 yr)
j = 41 (in 1 yr the product of 6 & 7)
------------------------------------------------
Response:
This is mostly a problem of logic
The multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, 99 etc
The only multiple with a prime number below it, is 44 and 88, with 43 being
the only value which gives 41 as the 2nd age, to satisfy the statement regarding
"product of consecutive numbers, 6*7 = 41 + 1
:
An equation perhaps:
j = a - 2
