Hello :
-1-(-4) =2-(-1)=5-2=8-5=3 ( arhtmitic sequence r= 3)
Un = U1+(n-1)r
U90 = -4+(90-1)(3)= 263
sum = n/2 (U1 +U90)
sum = 90/2(-4+263) = 11655

Answer:
Purse A will contain 2400 (by magic) and Purse B will have 64 pennies
Step-by-step explanation:
how this happened is, by magic Purse A went up by 200 every day for 7 days a week. 7*200 would be 1400 so you add that to the money from today and get 2400. Purse B somehow got from 1 penny to 64 in 7 days. The rule on this is to multiply by 2 every day. 1,2,4,8,16,32 and 64. have fun with your magic :3
