+129852 a) For the first series, the coloring pattern is
2, 4, 6
The algebraic expression is b = 2n where b is the number of colored blocks for figure n
For the second series we have
4,6,8
The algebraic expression is b = 2n + 2 where b is the number of colored blocks for figure n
b) For the first expression, 2 is the coefficient on the variable and we have no constant term
For the second expressiion, 2 is both the constant term and the coefficient
c) The coefficient in the first algebraic expression tells us that the number of blocks to be colored increases by 2 for each successive figure
The coefficient in the second algebraic expression also increases the number of blocks by 2 for each successive figure and the constant term tells us that we will increase the number of blocks by 2 from each corresponding figure in the first series
