Answer:
n=-5
Step-by-step explanation:
Isolate the variable
Answer:
7
Step-by-step explanation:
n= 4, a= -5, d = -1-(-5)= -1+5 = 4
Tn = a + (n-1)d
Tn = -5 + (4-1)4 = -5 + (3)4 = -5+12 = 7
Which ratio is equal to 6/15 as a fraction
6/15
divide by 3
2/5
Answer:

Step-by-step explanation:
1) 3 + 2 = 5 [Since the result is a natural number, it is a rational number]
2)
[ It has a square root that cannot be simplified further so the sum of this is an irrational one ]
3)
[The sum of it is rational i.e. in the form of p/q ]
4) -6+ (-3.251) = -6-3.251 = -9.251 [ Since the result is an integer, it is a rational number]
