Answer:
20260275
Step-by-step explanation:
the question is same as selecting 4 things from 150 things
= C(150,4). (nCr formula)
=[150×149×148×147]÷[4×3×2×1]
= 49×75×149×37
= 20260275
it depends on how big the triangle is if it is close to the same length of 20 go with 25 if theres a bigger difference go with 35. I think it would be 25 tho.
The 100th term would be 505.
