first term is given to us. A one is one and the other terms. We use this formula. So you two were doing that by using this formula where in plus one is acting Isar eight to, which means that our A N is acting, as are a one. So five times one minus three two a three is five times a to minus three. So five times two minus three So ten minus three seven a four, five times seven minus three seven because that they're a three value. So this is thirty five minus three So thirty two and then a five is five times thirty two minus three, which is one fifty seven.
