Question

Write down the first three terms of the sequences with the following rules a) 3n +7 b) 5n +8 Answer: Answer:​

Answer 1

a) 10,13,16

10,13,16b) 13,18,23

Explanation:

a) 3n+7 is the nth term

so to find the first term you need to say:3(1)+7 and it is equal to 10 which applies to other terms

second term is 3(2)+7=13

second term is 3(2)+7=13third term is 3(3)+7=16

b)5n+8 is the nth term

so to find the first term you need to say:5(1)+8 and it is equal to 13 which applies to other terms

second term is 5(2)+8=18

Third term is 5(3)+8=23
