The sequence below is the start of the triangular number sequence.Work out the next two number terms in the sequence.

The first four square numbers are shown below.Find the next two number terms in the sequence.

The first two terms of a sequence are 2 and 3. Starting from the third term, the term is the sum of the previous two terms. Find the 3rd, 4th and 5th term of the sequence.

Find a pattern in the sequence.  Use the pattern to show the next two terms.1, 3, 7, 15, 31, ___ , ___

c). Write a recursive function to find the nth “Triangular” number and write therecurrence relation for the function. [20%](Hint: A triangular number is the sum of itself and all other smaller numbers. Forexample, the triangular number of 4 is, 4+3+2+1 = 10.)

Find the nth term of a sequence.        2, 6, 10, 14, 18
