So first we need to find the term to term rule You can see that to get from 7 to 10 we add 3, to get from 10 to 13 we add 3, etc This becomes are coefficient of n (3n) Next we need to find out what we need to add to this number to get to the sequence 3*1+4= 7 3*2+4=10 So the nth term is 3n+4 where n is how far through the sequence you are

Start with finding your decimal multiplier Because she earns 1.5% interest per year, we have the decimal 0.015 Because we are adding this to our original amount our decimal multiplier is 1.015 Now use this formula (Original amount) * (decimal multiplier)^(number of ywars) This gives us 12000*1.015² =12362.70 This formula works for any compound interest scenario Hope this helps!

3n + 4 Explained: 1. This sequence jumps up in 3's. 2. The three times table has a formula of '3n' 3. The terms in this sequence are four more than the terms in the three times table. 4. The answer would therefore be '3n+4'

We can see that each term in the sequence we add 3. Also if we think about what number would come before 7, we can see 7-3=4. This tells us that the nth term is given by: 3n+4

Hey Chloe, To start this off, we can write 10% as 0.1. To find the increase of the value after one year you would do £100000 × 1.1. Therefore if we want 4 years we would do £100000 × 1.1^4

Yes We can find the value of n by equating our nth term to 602 3n+2=602 3n. =600 N=600/3 =200 So this is true for n=200

There must be a typo in this question.
