Q. c(n)=−6+5(n−1)Find the 8th term in the sequence. □
Identify Formula: Identify the formula for the nth term of the sequence.The given formula is c(n)=−6+5(n−1). This formula allows us to find the value of any term in the sequence by substituting the term's position (n) into the formula.
Substitute Term Number: Substitute the term number into the formula to find the 8th term.We want to find c(8), which means we substitute n=8 into the formula.c(8)=−6+5(8−1)
Perform Calculation: Perform the calculation inside the parentheses first, according to the order of operations (PEMDAS/BODMAS). c(8)=−6+5(7)
Multiply Result: Multiply 5 by the result from the previous step.c(8)=−6+5×7c(8)=−6+35
Add to Find Term: Add −6 to the result of the multiplication to find the 8th term.c(8)=35−6c(8)=29
