So in the given question we have a sequence and we are told to find the first five terms of the sequence.
00:10
The general term of the sequence is given as 4n minus 1 divided by n square plus 2.
00:22
So this is the general term.
00:24
Now we are told to find the first 5 terms of the sequence.
00:28
So we should just substitute n with 1, 2, 3, 4, 4.
00:33
And 5.
00:35
So a1 is equal to, which is the first term, is equal to 4 times 1 minus 1 divided by 1 squared plus 2.
00:48
So this would be equal to 4 minus 1 which is 3 divided by 1 plus 2 which is 3.
00:55
So a1 is equal to 1.
00:57
So the first term is equal to 1.
00:59
Now the second term is 4 times 2 minus 1 divided by 2 .2.
01:05
Square plus 2.
01:07
So this is equal to 8 minus 1 which is 7 divided by 2 square is 4.
01:14
4 plus 2 is 6.
01:16
So 7 by 6.
01:17
Now we have the third term which is 8 3...
