Q. g(n)=−50−15nComplete the recursive formula of g(n).
g(1) = \(\square\)
g(n) = g(n-1)+\(\square\)
Find g(1): To find the recursive formula for the sequence, we need to express g(n) in terms of g(n−1). First, let's find the value of g(1) by substituting n=1 into the given formula g(n)=−50−15n.Calculation: g(1)=−50−15(1)=−50−15=−65
Find g(2): Now, let's find g(2) to determine the common difference between terms. We substitute n=2 into the given formula g(n)=−50−15n.Calculation: g(2)=−50−15(2)=−50−30=−80
Calculate common difference: The common difference d between terms can be found by subtracting g(1) from g(2).Calculation: d=g(2)−g(1)=−80−(−65)=−80+65=−15
Write recursive formula: Now we can write the recursive formula. Since the common difference is −15, the recursive formula will be g(n)=g(n−1)−15.
