Well, honey, the first three terms for 3n + 7 are 10, 13, and 16. Just plug in n = 1, 2, and 3, and you'll see those numbers pop out like daisies in spring. Math can be a piece of cake once you get the hang of it!

To find the first three terms, plug 1, 2, and 3 in for n:
Term 1: 3(1) + 7 = 10
Term 2: 3(2) + 7 = 13
Term 3: 3(3) + 7 = 16
The first five positive integer terms for 3n + 4 are: 1 = 7 2 = 10 3 = 13 4 = 16 5 = 19
3,6,9,12.....
To find the first three terms of the sequence defined by the formula 100-3n, you simply substitute n = 1, 2, and 3 into the formula. For n = 1, the first term is 100-3(1) = 100-3 = 97. For n = 2, the second term is 100-3(2) = 100-6 = 94. For n = 3, the third term is 100-3(3) = 100-9 = 91. Therefore, the first three terms of the sequence are 97, 94, and 91.
3n + 14 = 83n = 8 - 14 = -63n/3 = -6/3n = -2The value of n is -2.
First you add 4 and 3 then you get 7 so you write the problem like this 3n + 7 and that is your answer
