HELP!!!!!(Question) The expression 4n-1 is a rule to describe a certain sequence. What are the first tree terms of the sequence.
A 3, 7, 11
B 4, 8 , 12
C 3, 6, 9
D 4, 7, 11

Answer 1

n = 1 we get 4(1) - 1 = 3
n = 2 ... .... 4(2) - 1 = 7

can you say which one it is?

Answer 2

Hmm B? maybe?

Answer 3

no - i've given you the first 2 terms so ..

Answer 4

the formula for each term is 4(n) - 1
so first term when n = 1 is obtained by replacing n by 1 - so its 4(1) - 1 = 3
