In this problem of sequence and series we have given that this is an is minus 2 n plus this is minus 2 n plus 8 and now we have to write the first 5 terms of the sequence assuming the sequence starts at here n is equal to 1 so the sequence starts at n equals to 1 and goes to 2 3 4 and 5 so here would be 1, 2, 3, 4, 5 that means a1, a2, a3, a4 and a5 that are in the 5 terms of this sequence.

So the first term that is a1, put here n is equal to 1, so this would be minus 2 plus 8 which is 6.
00:48
Now a2, the second term.
00:51
So here is the second term that is put here n is equal to 2.
00:55
So this would be minus 2 multiplied with 2, that is minus 4 plus 8 which is 2.

Simply 4 and now 8 3 that is the third term so put here n is equal to 3 so 2 multiplied with here minus 2 multiplied with 3 that is minus 6 plus 8 which is equal to 2 and now the 4th term put here n is equal to 4 so this would be minus 2 multiplied with 4 that is minus 8 so minus 8 plus 8 which is equal to 0 so this is simply 0 and now the 5th term is here now put here n is called to 4 so this would be minus 10 plus 2 which is minus 2.

So the 5 terms are here 5 terms...
