Question 1067945: make a conjecture about the number of squares in the nth sketch:
pattern1: 3 squares, pattern 2: 5 squares,pattern 3:7 squares and so fourth
MY ANSWER? I CAN CONJECTURE THAT IF THE PATTERN CONTINUES YOU CAN ADD 2 TO THE PREVIOUS COUNTING NUMBER TO GET THE NEXT TERM. is this right?

your conjecture is correct, but that doesn't tell you how many squares are in the nth sketch.

you can make a list as follows:


sketch number        number of squares           formula

1                   3                            2 * 1 + 1
2                   5                            2 * 2 + 1
3                   7                            2 * 3 + 1
4                   9                            2 * 4 + 1
5                   11                           2 * 5 + 1
6                   13                           2 * 6 + 1
.
.
.
n                   2 * n + 1

your next number of squares will always be 1 more than 2 times the sketch number.
