Which term of this sequence has value 8? |
2016-07-20 |
|
From Lauren: Hi there
Which term in the sequence -2; -5/3; -4/3 ; -1; ... has a value of 8.
Since term 2 and 3 of this sequence contain fractions which can be converted to recurring decimals. What is the best way to work out the common difference here.
I do however understand that to work out the nth term of an arithmetic series, the following formula Tn = a + (n-1)d. In this series a = -2 Answered by Penny Nom. |
