Q. Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n=1 for the first term.98,196,294,392,…an=_____
Sequence Type: We have: 98,196,294,392,…Is the given sequence geometric or arithmetic? 98,196,294,392,…Here, there is a common difference between consecutive terms.The given sequence is arithmetic.
Find a1 and d: Determine the values of a1 and d of the sequence. The first term, a1=98Common difference, d=196−98=98
