In an arithmetic sequence, the first term, a1, is equal to 5 , and the seventh term, a7, is equal to 29 . Which number represents the common difference of the arithmetic sequence?d=4d=5d=6d=7
Q. In an arithmetic sequence, the first term, a1, is equal to 5 , and the seventh term, a7, is equal to 29 . Which number represents the common difference of the arithmetic sequence?d=4d=5d=6d=7
Given terms: We are given the first term of an arithmetic sequence a1=5 and the seventh term a7=29. We need to find the common difference d. The formula for the nth term of an arithmetic sequence is an=a1+(n−1)d.
Express seventh term: We can use the formula to express the seventh term in terms of the first term and the common difference: a7=a1+6d.
Substitute values: Substitute the given values into the equation: 29=5+6d.
Solve for d: Now, solve for d: 29−5=6d.
Simplify equation: Simplify the equation: 24=6d.
Divide by 6: Divide both sides by 6 to find d: d=624.
Calculate d: Calculate the value of d: d=4.
