Question

write the following in set builder form:-
i) {x|x=5n,n € I (integer) and -3 <n less than equal to 3}
ii) { x|x=n²,n€W and n<5}
iii) {x|x= n² -2,n€ W and n<4}

Write the following set in set builder form:
i) {-14,-7,0,7,14,21,28}
ii) {1,2,3,6,9,18}

ik it's long but take ur time nd then send me plz​

Answer 1

i) {x|x=5n,n € I (integer) and -3 <n less than equal to 3}

ii) { x|x=n²,n€W and n<5}

iii) {x|x= n² -2,n€ W and n<4}

i) {x|x=-14 + 7 ,n € I }

ii)  For this question i guess your question is wrong because it is the Fibonacci series. But after 9, it should be 15 not 18.

{x|x=x + x-1(previous value) ,n € I }
