If a equals 4 and d equals -2 what is the first four terms of the arithmetic sequence?
6
What is the next number in this sequence 0 2 4 6 8?
What is the next number in this sequence 0,2,4,6,8......? Ans: The first number is 0. The second number is 2. The difference between those numbers is 2-0 = 2. The difference between the second and the third , the third and the fourth, the fourth and the fifty, the fifth and sixth is 2 only. So, the common difference is 2. That is 0+2=2, 2+2=4,4+2=6,6+2=8, then the next number in the series is 8+2 =10. The series continue like that only until infinity.
What is the common difference in the arithmetic sequence 10 8 6 4 ...?
It is negative 2.
What is the common difference for this sequence 13579?
2 common difference1 3 5 7 91 + 2 = 33 + 2 = 55 + 2 = 77 + 2 = 9
What is the nth term of the sequence 2 4 6 8?
Ok, take the formula dn+(a-d) this is just when having a sequence with a common difference dn+(a-d) when d=common difference, a=the 1st term, n=the nth term - you have the sequence 2, 4, 6, 8... and you want to find the nth term therefore: dn+(a-d) 2n+(2-2) 2n Let's assume you want to find the 5th term (in this case, the following number in the sequence) 2(5) = 10 (so the fifth term is 10)
