"GEOMETRIC PROGRESSION. A sequence of numbers in which any      number, or term, after the first can be obtained by multiplying its predecessor by a fixed number COMMRATIO.  Example 12, -24, 48, -96... or 27, 9, 3, 1...   Tosolve for progression enter any two term positions INDEX#A and INDEX#B and theirvalues TERM#A and TERM#B. TERM#N is the value for any index N and SUM is the sumof the progression up to and including term N. Type (F2) to return to helpfile."
