Hi my class is doing a unit on patterns with algebraic expressions. And i need to find a difficult expression
Figure# Term value
what is the algebraic expression and how did u do it? thank you.
It looks like a progression from 2-5, with each number being cubed.
2^3 = 2 * 2 * 2 = 8
If you let n stand for the number in your first column, then these would be the algebraic expressions.
(n + 1)^3 = 8
(n + 1)^3 = 27
And so on.
I hope this helps.
