Q. c(n)=94(−3)n−1What is the 3rd term in the sequence?
Identify term of sequence: Identify the term of the sequence we need to find.We are asked to find the 3rd term in the sequence defined by the formula c(n)=(94)(−3)n−1.
Substitute term number: Substitute the term number into the formula.To find the 3rd term, we substitute n=3 into the formula c(n)=(94)(−3)(n−1).c(3)=(94)(−3)(3−1)
Calculate the exponent: Calculate the exponent.Calculate the value of (−3)(3−1), which is (−3)2.(−3)2=9
Multiply by coefficient: Multiply the result of the exponentiation by the coefficient.Now, multiply the result from Step 3 by the coefficient (94).c(3)=(\frac{4}{9})\times 9
Simplify the expression: Simplify the expression.Simplify the multiplication to find the 3rd term.c(3)=(94)∗9=4
