Answer:
aₙ= 3n+1
Step-by-step explanation:
4 ,1 -2, -5 ,-8
AP with a₁=4 and d= -3
----------------
aₙ= 4+3*(n-1)= 4+3n-3= 3n+1
aₙ= 3n+1
Answer:
149 degrees
100
Step-by-step explanation:
17 + 14 = 31
The sum of a triangle is 180 degrees
so you subtract the given figure from 180 degrees
180 - 31 = 149 degrees
Since the last two digits is 49 which is less than 50 it will be rounded down to get 100
so the final answer is 100.
4>c/-1=4
The answer seems impossible to me but this is the closest I got.
Let x be that number
We know x + 5 = 12 ( the number plus five equals to 12)
=> x = 12-5 = 7
So, that number is 7.
