From the nth term equation given which consists of lower terms in the sequence the explicit formula is obtained. The lower terms are substituted in much lower terms and finally all terms on right are expressed in terms of n. This technique for solving using is called

What is the expression for the nth term of the given sequence 15, 12, 9, 6, …

A sequence is such that, the difference between successive terms form an arithmetic progression, then its nth term is given by:

What is the explicit formula for this sequence?2, 6, 18, 54, 162, …A.an = 3(2)(n – 1)B.an = 2(3)nC.an = 2 + 3(n – 1)D.an = 2(3)(n – 1)

The first four terms of a sequence are 11 21 31 41(a) Write down an expression, in terms of n, for the nth term of the sequence

The nth term of a sequence is given by the formulaTn = 34 - 8n. The first negative term of the sequence is -8 -2 -4 -6
