n = 1  we get  4(1) - 1 = 3
n = 2  ...   ....   4(2) - 1 = 7

can you say which one it is?

Hmm B? maybe?

cwrw238 · Answer

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

cwrw238 · Answer

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
