[takeahardlookatyourself]

it’s the number multiplied by the following whole number

[BSA_MClovin]

That the following numbers after the plus are reduced -1

[poxtaz.]

It adds the last result to the result of the addition example: 5+5=10+(20) 6+6= 12+(10+(20))

[j.wonhan]

20 = 4X5 = 4 + (4X4) = 4+4^2
30 = 5X6 = 5 + (5X5) = 5+5^2
42 = 6X7 = 6 + (6X6) = 6+6^2
56 = 7X8 = 7 + (7X7) = 7+7^2

Poorly written equations are not tricks.
