Arithmetic Sequences | How to find the nth term for Arithmetic Sequences IGCSE MATHS

in this session we have covered Arithmetic Sequences and how to find the nth term

1. check the difference of successive terms and preceding terms
if the difference is constant then we can say that the sequence is arithmetic Sequence
2. use the formula for the nth term
tn = a + (n -1)d
a is first term
d is common difference or first difference
tn is nth term
