Find the 25th term of the arithmetic sequence when a1 = -14 and d = -5

-106

Step-by-step explanation:

the arithmetic equation is

an=a1+(n-1)d

a(25th)=14+(25-1)(-5)

14+(24)(-5)

14+(-120)

14-120

a25=-106

easy

Step-by-step explanation:

25 terms=a+24d

=-14+24×(-5)

=-14-120

=-134

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
