Find the algebric expression for 15th term.
1 2 3 4 5 6 7 8 9 10
2 4 8
hold on, is the sequence 1,2,3,4,5,6,7,8,9,10,2,4,8........... or is it two different ones? besides wat grade r u in?
No these are two different rows. I am in grade 8 . it is part of ptterning.
To find the algebraic expression for the 15th term of the given sequence, we first need to understand the pattern in the sequence.
From the given sequence:
1 2 3 4 5 6 7 8 9 10
2 4 8
We can observe that each number in the first row represents the position of the number. So, the nth number in the first row is n.
In the second row, each number is obtained by multiplying the corresponding number in the first row by 2. So, the nth number in the second row is 2n.
To find the 15th term, we need to find the number in the second row corresponding to 15 in the first row, which is 15. So, the 15th term can be found by substituting n = 15 in the expression for the second row:
2n = 2 * 15
= 30
Therefore, the algebraic expression for the 15th term in the sequence is 30.
