21 and 13. The pattern is t(n) = (-n4 + 10n3 - 23n2 + 38n - 12)/12
An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
The normal way to write z times 19 in an algebraic expression is 19z.

Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
19
We could represent this in an Algebraic equation, where "x" is the missing number. If we write out the equation we will get:x + (-12) = 19. We simply add 12 to both sides.x + (-12) + 12 = 19 + 12.x = 19 + 12x = 31.When 31 must be added to -12 to obtain 19.
12 + 7 - 2 12 + 7 = 19 19 - 2 = 17 or 7 - 2 = 5 5 + 12 = 17

Let the number be x and so the expression is: x-19

from 12 to 16 is 4 then from 16 to fiftine is one then from15-19 is 4 so one so forth one is +4 the next is -1
