Answer:
49
Step-by-step explanation:
Method 1:
4,9,14....... has a common difference of of 5:
So, the first 10 numbers are 4,9,14,19,24,29,34,39,44,49.
So, the 10th number is 49
Method 2:
4,9,14....... has a common difference of 5:
That is going to be the coefficient of n in the nth term
Let's see the difference between this sequence and [tex]5n[/tex]
Position : 1 2 3 4
5n : 5 10 15 20
Sequence : 4 9 14 19
Difference: 1 1 1 1
The nth terms going to be 5n-1
We should now put 10 instead of n
5(10)-1=50-1=49
