chi sun is making patterns
the table is the for the number of dots in each pattern
pattern number | 1 2 3 4 5
number of dots | 5 8 11 14 17
which pattern number has 32 dots?
+33661 Well, when n = 6, the number of dots will be 17 + 3 = 20
when n = 7, the number of dots will be 20 + 3 = 23
... you could continue this way until you reach 32.
Alternatively, you could notice that the n'th term is given by 2 + n*3. where n starts at 0. Set this equal to 32 and solve for n.
That is 2 + n*3 = 32 so what must n be?
+33661 Again, look at the difference between each of the numbers of dots in the second row of the table.
+33661 Well, when n = 6, the number of dots will be 17 + 3 = 20
when n = 7, the number of dots will be 20 + 3 = 23
