22, 76, 238, 724, 2182
to generate the terms substitute n = 0, 1, 2, 3, 4 into the recursive function
= 3
+ 10 = ( 3 × 4 ) + 10 = 22
= 3 + 10 = (3 × 22)+ 10 = 76
= 3 + 10 = ( 3× 76) + 10 = 238
= 3 + 10 = ( 3 × 238) + 10 = 724
= 3 + 10 = (3 × 724) + 10 = 2182
It appears that BEF is marked the same as BED. BED is 180 - 90 - 50 which is 40. angle BEF = 40. If triangle BED is congruent to triangle BEF, which it is, then FE is the same measure as DE, and it just so happens that DE is marked congruent to CD which is 7. Therefore, FE is also 7.
What is the sequence 0, 1, 4, ?, 16, ?, 36, ?, ?, 81, ?

It is the square of the integers starting from 0 to 10 as follows:
0^2 = 0
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
5^2 = 25
6^2 = 36
7^2 = 49
8^2 = 64
9^2 = 81
10^2 = 100
So An = n^2
Hope that helped!
(a) 10 = 2x5
(b) 37= 1x37
(c) 25=5x5
