The Given Sequence is an Arithmetic Sequence with First term = -19
⇒ a = -19
Second term is -13
We know that Common difference is Difference of second term and first term.
⇒ Common Difference (d) = -13 + 19 = 6
We know that Sum of n terms is given by : 
Given n = 63 and we found a = -19 and d = 6






The Sum of First 63 terms is 10521
Answer:
Step-by-step explanation:
Here, the vertical space between two consecutive stairs in first 10 stairs =
⇒ The total vertical distance for 10 stairs = 
Also, The vertical space between two consecutive stairs for last 5 stairs = 
⇒ The total vertical distance for 10 stairs = 
Thus, The total vertical distance = Total vertical space for the first 10 stairs + Total vertical space for the last 5 stairs
= 
= 
= 
=

Bear in mind that multiplying anything, and anything whatsoever by 1, has a product of the anything itself.
so, let's multiply 2/3 by 1 then and check about,
Answer:
96 bars = 10cent each (dime/pence etc) 10.2604166667 each
Step-by-step explanation:
if the cereal bars are accounted for 24inch x 4inch and 4inch lengths seem appropriate length, Then we can account for 1inch x 16 inch widths being 1'' wide each. 6 x 16 = 96 and 96/388 = 4 being the length.
Extended: Area of pan 24 x 16 = 240+148= area of 388in^2
96 bars costing ($9.85) 985/96
