What is the rule to find the nth term?
The nth term of an arithmetic sequence is given by. an = a + (n – 1)d. The number d is called the common difference because any two consecutive terms of an. arithmetic sequence differ by d, and it is found by subtracting any pair of terms an and. an+1.
What is the first 3 terms of 3n 2?
To find out the first three terms of 3n + 2 substitute 1 ,2 and 3 into the equation. 3(1)+2=5 3(2)+2=8 3(3)+2=11 As you can see the sequence goes up in 3s 5 ,8, 11 To find out the 10th term you also substitute 10 into the equation so 3(10)+2=32 Hope this helped!
Which is the correct answer to the sequence 17?
This is really hard to spot if you don’t see it at once and also requires some of the box thinking. This sequence consists of the first prime numbers. Therefore the correct answer is the next prime number in the sequence is this is “17”. 8. This sequence consists of square numbers, but very other number is subtracted by 1.
How are the numbers in the sequence 14 related?
14 This sequence consists out of two alternating series. The first series shows the relation between the 1st and 3rd number, 3rd and 5th etc. in this case this following relation exists: 10-15-20 with an addition of 5 every time. The second series shows the relation between the 2nd and 4th number, the 4th and 6th etc. in this case 45-38=7.
Which is the best description of a sequence?
What is a Sequence Number? Number sequence is a progression or an ordered list of numbers governed by a pattern or rule. Numbers in a sequence are called terms. A sequence that continues indefinitely without terminating is an infinite sequence, whereas a sequence with an end is known as a finite sequence.
How to find the sequence of three numbers?
Three consecutive numbers, 24, 28, and 32, are examined to find this sequence pattern, and the rule obtained. You can notice that the corresponding number is obtained by adding 4 to the preceding number. The missing terms are therefore: 8 + 4 = 12 and 16 + 4 = 20
