its +2, +2, -1... so the next is 10
Finding the nth term is much simpler than it seems. For example, say you had the sequence: 1,4,7,10,13,16 Sequence 1 First we find the difference between the numbers. 1 (3) 4 (3) 7 (3) 10 (3) 13 (3) 16 The difference is the same: 3. So the start of are formula will be 3n. If it was 3n, the sequence would be 3,6,9,12,15,18 Sequence 2 But this is not our sequence. Notice that each number on sequence 2 is 2 more than sequence 1. this means are final formula will be: 3n+1 Test it out, it works!
The sequence n plus 3 can be represented as 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ... The 10th term of this sequence can be found by substituting n = 10 into the formula, which gives us 10 + 3 = 13. Therefore, the 10th term of the sequence is 13.
The Fourth Triangular Number is 10.
9+1=10, 8+2=10, 7+3=10, 6+4=10
next in the sequence: 10,20,30,20
10
5
5
10
22
15
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
The next number in the sequence is 480
The next number in the sequence is 27.
The pattern in the sequence is that each number is divided by 10 to get the next number. Therefore, the next number in the sequence would be obtained by dividing 4 by 10, which equals 0.4.
