To find the number of terms in the series 20,1913,1823,… whose sum is 300, we can follow these steps: Step 1: Identify the first term and common differenceThe first term A of the series is:A=20The second term is 1913, which can be expressed as:1913=19+13=583The third term is...
To find the common difference D:D=a2−A=−9−(−12)=−9+12=3 Step 2: Use the formula for the nth term of an A.P. to find the number of terms (N). The nth term of an A.P. is given by:an=A+(n−1)DWe know the last term an=12. Plugging in the values we ...
Find the sum of the two middle most terms of the AP ( frac 4 3 1 frac 2 3 ldots 4 frac 1 3 ) - Given:Given A.P. is $-frac{4}{3}, -1, -frac{2}{3}, -frac{1}{3}, ..., 4frac{1}{3}$.To do:We have to find the sum of the two middle terms of th...
the problem follows an Arithmetic Progression (AP). We find the ${{n}^{th}}$ term of the series by using the first term and common difference of the given series. Once, we find the ${{n}^{th}}$ terms, we use the sum of n terms of Arithmetic Pro...
Graduate entry tests such as the GMAT, GRE and others are an important part of the admissions process for some PhD programmes. Our guides explain who has to take a test and how they work.
ROME (AP) — Italian military vessels searching Monday for an infant missing from a migrant boat that capsized last week instead found four decomposed adult bodies apparently from a previous shipwreck. The Italian daily La Sicilia online news said the bodies of two women and two men were ...
You don't need to be a math whiz to solve this problem: Who has better odds of gaining acceptance at the college that's the best match: the high school senior who applies to 25 schools indiscriminately or the one who applies to a carefully whittled-down list of seven?
SMALL(IF((C3:AM3>=18)*(D3:AN3>=18)*(E3:AO3>=18)*(F3:AP3>=18), COLUMN($A$1:$AK$1)),1)),B3), "N/A") Hi Brian. You are welcome. The SMALL part of the formula would extend like in above formula. The other parts have to be adapted accordingly....
As already mentioned, the FIND and SEARCH functions in Excel are very much alike in terms of syntax and uses. However, they do have a couple of differences. 1. Case-sensitive FIND vs. case-insensitive SEARCH The most essential difference between the Excel SEARCH and FIND functions is that ...
