:shrug: Ok I may have to adjust the formula, 40 years ago which is divisible by the numbers 2, 4, 5, & 8, add the first and third number in the sequence it makes the lucky number 7 which must be a good omen tomorrow.
ABBA won in 1972 at the Dome in Brighton, 42 years ago, which is divisible by the numbers 2, 3, 6 & 7, and with seven being a lucky number it must be a good omen for tomorrow.
