### What is the nth term of the sequence -4 4 12 20 29?

The nth term of the sequence -4 4 12 20 29 is 8n+12 because each time the sequence is adding 8 which is where the 8n comes from. Then you take 8 away from -4 and because a - and - equal a + the answer is 12. Which is where the 12 comes from. Hope I helped.

### What is the nth term for 98 94 90 84?

The nth term is -4n+102. Method: To find the nth term (Tn) of the sequence, multiply n by the pattern of change in the sequence from left to right (-4). Then, substitute n for a term, for example, term 2. Follow the first step (-4n) which will give -8. Then you add or subtract to equal the number of that term (94). -8+x=94. x=102. Therefore, the formula for the nth term is -4n+102. To prove… Read More

### What is the nth term for the sequence 7 12 17?

It seems that the term increases 5 at a time, so (if this tendency continues) it's quite clear that the sequence is of the form 5n+k, for some constant "k". With a little experimentation, you can find that "k" should be 2.
