9 plus 7 equals 144. The series is formed by multiplying the first number with the sum of both numbers. 2(2 + 3 ) = 10 : 7(7 + 2) = 63 : 6(6 + 5) = 66 : 8(8 + 4) = 96 : Then 9(9 + 7) = 144.

because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6
You add 1 plus another one and you get 2
a number equals 2
5 is the sum. 2 and 3 are the addends.
