1.	If a sequence is in the form 2*5^n then which of the following may be the sequence?(a) Arithmetic progression(b) Geometric Progression(c) Harmonic Progression(d) Special ProgressionI have been asked this question in examination.The above asked question is from Geometric Progression(G.P.) topic in portion Sequences and Series of Mathematics – Class 11
Answer» Right answer is (b) GEOMETRIC Progression To EXPLAIN I WOULD say: If an = 2*5^n then a1 =10, a2 = 50, a3=250. This is a geometric progression with first TERM 10 and common ratio 5.
