Answer:
Option (b) is correct.
The general term of the sequence is 2n
Step-by-step explanation:
Given : The sequence 2, 4, 6, 8, 10, . . .
We have to find the representation of the general term of the given sequence 2, 4, 6, 8, 10, . . .
Consider the given sequence 2, 4, 6, .....
The general term of an arithmetic sequence is given by
where, a = first term
d is common difference
For the given sequence a = 2
and d = 2
Then
Thus, The general term of the sequence is 2n
Answer:
Correct choice is B
Step-by-step explanation:
For the numbers -1 and 59, find the difference 59-(-1):
since 59-(-1)=60 and (two arithmetic means tells you there will be three intervals), two arithmetic means will be
The only correct sequence is -1, 19, 39, 59.
Given :
A vector v = 10i - 24k.
To Find :
A vector of magnitude 3 in the direction of v = 10i - 24k.
Solution :
Unit vector in the direction of vector v is :
Now , vector of magnitude 3 in direction v is :
Hence , this is the required solution .
