A right triangle with coordinates A (–1, 4), B (–1, 8) and C (3, 4) is first rotated 90 degrees counterclockwise and then translated 2 units left and 3 units down to form triangle A’B’C’. What is the measure of angle B’A’C’, in degrees, in the result

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for
