Answer:

The nth term of sequence is 3n^{2}+7

Step-by-step explanation:

We need to find out the general recurrence relation of sequence:

10, 19, 34, 55

if we see pattern of sequence that every square of each number 'n' is multiple of 3 and addition of 7

check this pattern by 3n^{2}+7

For n=1

3n^{2}+7

3(1)^{2}+7

3+7

10

For n=2

3n^{2}+7

3(2)^{2}+7

3\times 4+7

12+7

19

For n=3

3n^{2}+7

3(3)^{2}+7

3\times 9+7

27+7

34

And so on..

Therefore, the nth term of sequence is 3n^{2}+7
