- 1Geometric progression means we....Multiply or divide by the same value
(opposite to arithmetic progression) - 2The first term of a geometric sequence is defined by.....a
- 3The common multiplier of a geometric sequence is defined by....r
- 4To find un in geometric progression, we use....un = ar^(n-1)
- 5In general, a geometric sequencea , ar , ar^2 , ...... , ar^(n-1)
- 6To calculate the sum of the first n terms in a geometric sequence, we use...Sn = a(1-r^n) / (1-r)
- 7The sum to infinity of a geometric sequence is....a/1-r
