Income Tax inspector, Assistant in AFHQ, Railway. Examiner, PO amd Excise inspector used to be considered best posts but now you are asking you don't want to give CPT but from 2017 CPT is must for these also. So, now it's better to give CPT from cgl17

  1. SEQUENCE AND SERIES Class -(6 (Geometric Proqression)


  2. GEOMETRIC PROGRESSION A sequence (finite or infinite) of non-zero numbers in which every term, except the first one, bears a constant ratio with its preceding term, is called a geometric progression, abbreviated as G.P. The constant ratio is usually denoted by r and is called the common ratio of the G.P. i Binee


  3. nth term of an Geometric Progression 2 a n-l Point to remember 1. If a is the first term and r is the common ratio of a G. ., then the G.P. can be written as n-I a,ar, ar , or?- - , OT , -- . (ato)


  4. Point to remember 2. Choosing number in G.P. 2 3. Three number a, b and c are in G.P. if 2 b ac

  11. If 5th and 8th terms of a G.P. are 32 and 256 respectively, then the 4th term of the G.P. is (a) 8 (b) 12 (c) 16 (d) 20 and Com non s = are =32 - dvide aru32 Tu= a.rs 2


  12. The 3rd term of a G. P. is the square of the first term. If the second term is 8, then the 6th term is (a) 128(b) 64 (c) 32 (d) none of these. T. 2 T. -r ~2- 2 128
