Answer:
For any sequence, the first term a1 is when n=1, the second term a2 is when n=2 and so on.
For your first sequence a1=(−1)1+1(1+4)=5
a2=(−1)2+1(2+4)=−6
continue for each term
Step-by-step explanation:
Replace n by the whole number indicating the term you are calculating. A sequence is a list of terms in a specific order, the order is given by n, the value is given when you substitute n into the formula.
