Explain how to find the common difference of an arithmetic sequence How can you determine whether the arithmetic sequence has a positive common difference or a negative common difference?
For any index n (>1) calculate D(n) = U(n) - U(n-1). If this is the same for all integers n (>1) then D is the common difference. The sign of D determines whether the common difference is positive or negative.
What is the difference between arithmetic progression and geometric progression?
In an arithmetic progression the difference between each term (except the first) and the one before is a constant. In a geometric progression, their ratio is a constant. That is, Arithmetic progression U(n) - U(n-1) = d, where d, the common difference, is a constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1) + d = U(1) + (n-1)*d Geometric progression U(n) / U(n-1) = r, where r, the common ratio is a non-zero constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1)*r = U(1)*r^(n-1).
What is first difference?
In a sequence of numbers, a(1), a(2), a(3), ... , a(n), a(n+1), ... he first differences are a(2) - a(1), a(3) - a(2), ... , a(n+1) - a(n) , ... Alternatively, d the sequence of first differences is given by d(n) = a(n+1) - a(n), n = 1, 2, 3, ...
What is the definition of an arithmetic sentence?
An arithmetic sequence is a sequence of numbers such that the difference between successive terms is a constant. This constant is called the common difference and is usually denoted by d. If the first term is a, then the iterative definition of the sequence is U(1) = a, and U(n+1) = U(n) + d for n = 1, 2, 3, ... Equivalently, the position-to-term rule which defines the sequence is U(n) = a + (n-1)*d for n = 1, 2, 3, ...
Finding the nth term of a sequence in maths?
a + (n-1)d = last number where a is the first number d is the common difference.

a + (n-1)d = last number where a is the first number d is the common difference.
What is the nth term formula of 100 89 78 67?
clearly the given series is an arithmetic progression with a common difference of -11,that is every term is obtained by subtracting 11 from the previous term for any A.P, n-th term is a(n)=a(1)+ (n-1)d where a(1)=first term and d=common difference here a(1)=100, and d= -11 so, a(n)=100+(n-1)x(-11) or, a(n)=111-11n
What is the formula to find sum of n even numbers?
Sum = n/2[2Xa1+(n-1)d] where n is last number, a1 is the first number & d is the common difference between the numbers, here d=2 for the even /odd numbers. Sum = n/2 [2Xa1+(n-1)2]
How do you get the general term of an arithmetic sequence?
The general (or nth) term is given by the equation t(n) = a + (n-1)d where a is the first term and d is the common difference between successive terms.
What is the difference bw overall n category rank in aieee?
Catagory rank is your rank in your category(ie - General, SC, ST, OBC). Overall ranking is your rank in all category, including, general, ST, SC, OBC.
If the first term of a sequence is 8 and the 10th term is 53 what is the common difference?
I am assuming this is an arithmetic series. Use the formula nth term = a + (n-1)d where a is the 1st term, and d is the difference between each term. 10th term = 8 + (10-1)d ==>8 +9d=53 ==> 9d = 53-8 = 45 ==> d = 5 The difference is 5.
How do you find the nth term in an arithmetic sequence?
tn = a + (n - 1)d where a is the first term and d is the difference between each term.
