Activity 1.
A. Formulate a formula for the following arithmetic sequence.
5
31
1.) 3, 10, 17, 24, 31...
Position of
3
4
term
Value of 3
10
17
24
term
So the number is increasing by
Since the number is adding by. therefore it is
So, the first term is 1 x
the second term is 2 x
the third term is 3 X
We notice that the answer is in excess of
Therefore, the formula is
