3. Write the following Arithmetic Sequence using an Explicit Formula: a1 = 14, an = an-1 - 6 an = 6 - 14(n - 1)
an = 14 + 6(n - 1)
an = 6 + 14(n - 1)
an = 14 - 6(n - 1)

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
