Step-by-step explanation:
2/3=0.66666666666
4/5=0.80000000000
10 rational numbers between them
0.7, 0.71, 0.72, 0.73, 0.74, 0.75, 0.76, 0.77, 0.78, 0.79
You put your like terms together so, you do the opposite of addition which is subtraction.
So you subtract 6 on each side, and -28-6 is -34
so now you have 2n=-34 and since 2 has the variable you have to divide by 2 on each side so how you have n= -34÷2
so 34÷2= 17 and since the terms are unlike you have to put a negative sign
so n=-17
Answer:
a = 12 and b = 18
Step-by-step explanation:
Given that,
8,a,b,27 are in geometric sequence.
For a GP, the nth term is given by :
Put n = 4
Put n = 2,
Put n = 3
So, the values of a and b is 12 and 18 respectively.
