The pattern is:
4, 8, 15, 25
Is the formula:
2.5n + 1.5n???
If you are wondering what the standard formula is, check my previous question.
Thank you! :-)
To determine if the given formula, 2.5n + 1.5n, correctly represents the pattern 4, 8, 15, 25, we can substitute the values of n into the formula and check if it produces the corresponding terms.
Let's evaluate the formula for each value of n:
For n = 1:
2.5(1) + 1.5(1) = 2.5 + 1.5 = 4
For n = 2:
2.5(2) + 1.5(2) = 5 + 3 = 8
For n = 3:
2.5(3) + 1.5(3) = 7.5 + 4.5 = 12
From the calculations, we can see that the formula 2.5n + 1.5n does not produce the correct values for the pattern. The formula should yield 4, 8, 15, 25, but it instead gives us 4, 8, 12.
Therefore, the formula 2.5n + 1.5n is not correct for representing the given pattern.
