Find the 51st term of the arithmetic sequence -17, -25, -33

The explicit formula is an = −8n − 9

So plug in 51 as n

-8(51) - 9

-408 - 9

-417

51st term = -417

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
