Question

Write down an expression for the nth term of the following sequence 7,16,25,34,43

Answer 1

Answer:

So in this sequence, we are adding by 9 in each term

So our pattern is: 7 , 7 +9 , 7 + 2(9) , 7 + 3(9) .....

hence, we can write it as: 7 + $9^{n-1}$ where n is the number of the term you want
