1:
For every integer k from 1 to 10 inclusive, the k th term of a certain sequence is given by (-1)^k+1 (1 over 2^k). If T is the sum of the first 10 terms in the sequence then T is:
1/ Greater than 2
2/ Between 1 & 2
3/ Between 1/2 & 1/4
4/ Between 1/4 & 1/2
5/ Less than 1/4
2:
n is a multiple of 5 and n = p^2 * q where p and q are primes. Which must be multiple?
1/ p^2
2/ q^2
3/ p*q
4/ p^2 * q^2
5/ p ^3 * q
Any help would be greatly appreciated!!!
Thank you,
